How To Do 6 Speed To 7 Speed Freewheel Conversion
Vložit

- How to convert a bike from a 6 speed freewheel to a 7 speed freewheel. This is a vintage Lotus road bike (made in Japan). It was a 12 speed (2x6). I converted it to be a 14 speed bike (2x7). I upgraded it with a 7 speed freewheel and 7 speed SIS downtube shifters. The rear derailleur was already SIS compatible. And the chain had been recently replaced, and it was 7 speed speed compatible. This is a pretty easy upgrade.

Converted my 2x6 bike into 2x7 because of this video, bought the same freewheel. Thanks for the help RJ! Greetings from PH
Hi Mr RJ. You sir are the best! i was thinking of changing my bicycle from a 6 speed to a 7 speed but did not know how and as usual i check youtube and here a video yet again by you showing how to do it, you may not know this but through all your videos i have managed to learn so much and even apply it to my bike, I just wanna thank you so much for doing this kind of video and helping out beginers like me to fix our bike ourself. So thank you so much and keep doing what you do!!!
Han Sykes Thanks!
RJ Thank you so much for these videos. I bought parts to repair my bike and I found literally everything I need on your channel
RJ explains it better than the park tool channel
What I like in all of your videos is explenation of all of potencial problem during maintaining and upgrading and solving it with ease.And also I like that according to your time,you are trying to cover all parts of a bicycle,no matter is it maintaining or upgrading.Thank you for all of your advices.
Brilliant video. It popped up just when I needed it too. I've been contemplating what to do with an old 18 speed hybrid, and now it's going to be upgraded.
That was great. When I buy a machine be it used or brand spanking new I will be checking out your videos for help and advice. Great lesson.
Helped me a lot, Sir! I have the same initial state...same derailleur. Excellent content.
I have the same Lotus just in brown/pink. Love this bike. I lucked out just swapping out the whole wheel from another bike. Bonus was also upgraded from freewheel to hyperglide!
I did all the procedure on this video to my brother's bike 6 to 7 speed but i used a spacer and it worked the derailleur adjustment is easy
Thank you rj
great, very descriptive video. glad you included cable and shifter replacement. sounds like the chain is rubbing in the smaller cogs though.
hello, this is very helpful especially this times of pandemic, i've watch all your vids are applied what i've learned on my bike!
Really nice bike too! Thanks, these videos are great!
Doing this today with your help to an '86 Trek Elance! Thanks
Going to try to go from a 2x6 to a 2x7 on my 83 Coventry Falcon. I want to use some ST-A070 Integrated levers as well. I'll be using this video. Thanks RJ.
i went from a 1×6 to a 1×7 on my Btwin riverside 100 ,, thanks RJ..
thank you Rj! you helped me everytime! I'm from Phillipines i love your vids because they are very helpful to me!
Sir na try nyo na po 7s cogs thread to 8s cogs thread?
Very helpful, no-nonsense videos... Thnx man
i have seen all your vids .love them all
Nice bike, I had a Lotus Odyssey back in the day
@Guillaume Bourdel, I found this stand cheap on ebay. It was a bit rough. The bottom part had some rust. So I cleaned it up and repainted the bottom part. It was originally the same gray as the top part. I keep the Park Tool stand in the house and this one in the garage. That way I don't have to drag the Park Tool stand in and out. The Park Tool stand is much nicer. This one doesn't hold the bike quite as solid as the Park Tools stand. I still have my homemade stand which I used for years. It is currently holding a Trek 520 frame that I plan to build up.
Cool! I have to tell you the stand you made was one of the best I've seen (and I've researched DIY stands for quite a bit!) and I used it as a base for mine. I wasn't quite sure about the plastic T joint to hold the bike so I installed pipe clamps instead. It never failed me and although it's not as practical as a "real" one it still does the job very nicely. I like how it can be taken apart too to store in tight space like the one I have. It sure makes any repair and cleaning easier!
I think some of the DIY stands around the net were based on mine. I posted these plans back in 2007: www.bicyclebikes.com/bicycle-repair-stand-plans.html
+RJ The Bike Guy got a couple if questions above if you could help?
Nice tutorial there! Is that a new stand you have? Didn't you use to have a Park tool one?
I made mine based on the DIY version you made some time ago with a few modifications and it works great for the little money I have for this :)
I have bikes from every era, carbon, alloy, steel & those old Japanese derailleur r the best
I wanna know if I can put a cogset on a Japanese bike (｢`･ω･)｢
Great video🤙🤙
Thank you RJ.... Good job👌👍👏
Very educational, and really helps Me. Thank You very much....
Thanks for the great vid
I noticed this has a biopace crankset. What do you think about those? I have one but I am thinking about changing it for something more standard.
hey there,
Can you make a video where you need to put a spacer?
or if you already have please may i know the link?
thanks.
This can really help converting from grip shift to trigger shift. I don't like those revoshifts.
I'm planning this with a 1970s friction-shifting road bike. I assume the derailleur and shifters can stay, and I just adjust the limit screws. Is that right?
This guy is the best .
I'm converting from a 7 speed to an 8 speed and the chain DOES hit the frame. Since I'll be adding a spacer on the drive side, shouldn't I add one on the other side as well? That will then mean the disc brake caliper will need adjusting or shimmed right?
Right up my alley, I just picked up a Bottecchia 6 speed bicycle and I want to covert it to 7 speed.
I assume the method would be similar for vintage 5 to 6 speed conversion?
Hi RJ can i use a a 7 speed derailleur on a 8 speed on a mountain bike
I recently bought a bike that has a Shimano SIS rear derailleur, a 7speed shimano freewheel but a SunRace 6speed grip shifter. Is it a good idea to switch to a 6speed freewheel and keep the shifter or should I replace the shifters to match the cogs? Which one is more cost effective?
Hey RJ, can i have an 8 speed downtube shifter with 7 speed setup? And whats the deal with picking front derailuer? ive been hearing low vs high and dont seem to understand it.
Hi, thanks for the video . I have a 1984 Cannondale SR 300. I would like to change my crankset because it's to hard of gear for me 52/42. What would I need to do for a triple chainset. I have friction shifters and derailleurs. Thanks!
FYI I have a bike that has a 6 speed shimano 600 uniglide rear hub with 7 cogs on it. You need to use slightly thinner spacers between the cogs (specific to 7-sp). The small threaded cog has enough space to screw on a few threads, which seems safe to me. I've put a few thousand miles on it with no issues. I don't know if this would work for all 6 speed uniglide hubs, but it works for mine.
I also wonder if you just have a non-indexed friction shifter, if there's many RD's designed for 6 speed that can't handle 7 cogs? don't know if there's any leeway for adjusting the limit screw.
No Grease or Anti-sieze compound on the threads?
great!! and what about install a 7 speed shimano freewheel with "megarange"? do i need another derailleur? or just an extender? i have a shimano 105 of the 90's
czcams.com/video/9R1CVWcgu_M/video.html
Another great video! Reason to do this is just to give a bigger cog for hills, right? I have an '87 Trek with Suntour a5000 derailleur (AccuShift system?) and DT shifters. 6 speed indexed shifter. Do you think I could just get a new pair of 7 speed suntour shifters (or even just the right side one) that would work with my existing derailleur? I see lots of 7 speed suntour accushift DT shifters on ebay. Thanks for any info you can provide!
You can have a bigger cog with 6 cogs. 7 cogs give you more gearing options. And more options for indexed shifters. You would have to research that. I am guessing if it is accushift, it will probably work. I like the Shimano SIS indexed stuff.
nice video and nice bike. What kind of tubing is that Lotus bike from JPN?
Cro Moly.
Hey, I have a 6 x 3 speed bicycle but it's 5 years old now. I need to change the shifters so is there any chance by which I can convert it into a 7 x 3 speed bicycle. I also need to repair my breaks so I was really considering the shimano combo shifter.
Or can I use the shimano combo shifter for a 6 x 3speed bicycle?
Thanks. :)
hi I can only have one bike if I can only have one bike what bike should I own I live in P.A northeast philly their are climbs but nothing huge
Hello there i can’t seem to figure out why once I put the 7 speed on my wheel is cause the axle to Solon with it any help?
Can you use the 6s shifter with a 7s freewheel if you turn off your indexing?
Hi RJ. If the chain is rubbing what type of spacer am I looking for to be able to put on? Is it a standard washer or is it a specific rear axle spacer?
Just a 1 or 2mm axle spacer.
There's even 11 speed freewheels nowadays, are they compatible with 6 speed freewheel hubs? I need more clarification about the spacer thing when converting a 6speed to 7 speed 😭
Nice Explanation, But... is it possible that you name the tools and the new parts so it's easyer for the readers what they need to do it yourself.
There's alot of fake parts on the internet.
I myself have a vintage peugeot city bike from 1975, made in france with that 6 speed freewheel (Shimano MF-HG20) with Shimano Positron PPS derailleur and need a new freewheel. If you could advise me which Freewheel remover (mayby FR-1) and which freewheel i need (mine is 14-32).
Great video! Merry Christmas! I have a 6 speed freewheel bike (an old big box bike) and a good 8 speed shimano acera shifter. It would be less expensive to do an 8 speed freehwheel conversion than a 7 speed freewheel. Is it feasible without needing to redish the wheel? I got a steel frame that I can extend.
You will need a new wheel. 8 speed hubs are wider than 6/7 speed hubs. And generally 8+ speed are cassettes, not freewheels. There are 8+ speed freewheels, but they are usually cheap junk, and the longer axle is prone to bending.
what about long/short cage derailleurs?,just realised u didn't mention this?,thought most 6 speed derailleurs could be adjusted to accommodate 7 speed just like the old tourneys which were for 6/7 speed?
+neil crompton Long cages are to take up more chain where there are large differences in gearing (big chain ring/big cog versus small chain ring/small cog). Nothing to do with this video. (see my vid on chain sizing czcams.com/video/ELsKrgTt0oY/video.html) A rear derailleur in the case of this video needs to be able to reach all the cogs. A 6 speed RD may or may not be able to move far enough to reach all 7 cogs.
Hey RJ, I have a few quick question for you about mods on my Citizen Tokyo Bike, which I got really cheap. The standard equipment is 16 inch wheel freewheel, Shimano 14-28T 6 spd, the stock tires are 16" x 1.75" 45 psi. stock plastic foldable pedals, Alloy V-brakes and 170mm alloy crank arms with 48T alloy chainwheel. Cool bike, but too slow and a little heavy. I'd like to upgrade a few components for a little more torque. Of the few blogs, I read, recommendations have been made for a 11-28 freewheel, 7 speed and 55 T chainwheel. My questions are has anyone attempted this project? If so, did this combination make a difference? Lastly, to reduce the cost of overspending, the best place to source components? Thank you.
My bike has a steel frame and I have an old 8 speed trigger shifter laying around. Is it possible to do a 6 to 8 speed (both freewheels) conversion?
Possible, yes. Advisable, no. If you want 8 speed, get a wheel with 8 speed cassette. You will have to expand the frame. czcams.com/video/QwxEPRk3LFg/video.html
I have a shifter with 7 speed and a rear wheel with 7 cassette, I don't want to use the 7th gear on 7th cassette I want it to start it from the 6th cassette . How do I do that?
can I go from 7 to 6 speed? parts here are scarce my 7 speed is already worn out, and 6 speed is only the available option.
Is 7speed sti or shifters is compatible to 8speed cogs plss answer me thanks ☺️
assuming your not using an indexed shifter(using a friction shifter) is replacing the rear derailleur necessary when going from a 6 to 7 speed freewheel. this is on a 1984 schwinn world sport, which is equipped with a Suntour friction quill stem mount shifter, and a Suntour AR rear derailleur. the front derailleur is a Suntour AR as well.
Maybe, maybe not. Depends whether the derailleur will reach all the cogs.
well! we'll find out tomorrow when i go into the shop! thanks dude!
hey just wanted to let you know i was sucessfully able to convert the world sport to 7 speeds! next step is 9 speed!
Cool!
Does anyone know the exact model and year of this Lotus bike in the video?
I found 8 and 9 speed freewheel for sale. Can you do a 6 to 8 or 9 speed freewheel conversion without changing the hub (will there be enough space)?
Freewheels above 7 speed are generally cheap junk. And then you would have issues with bent axles which is why they moved away from freewheels for more gears.
Are the sprockets the same width / thickness? Anything to look out for in this regard?
The cogs are spaced different. www.sheldonbrown.com/cribsheet-spacing.html
How can we know if a derailleur is conversion ready? And you said that 8-9 speed freewheel are junk. How about the modern ones like on the Schwinn Traxion?
If you want 8+ speeds get a cassette wheel. czcams.com/video/qcgz3-XyNkI/video.html
the shimano freewheel tool the same for all shimano wheels and if so would it be a fr1 free wheel tool
The Park Tool FR1 or FR1.3 should work for most if not all Shimano Freewheels.
Great video RJ. Would you happen to know if Shimano made a 7 speed freewheel in the 600 series? I've looked for one on ebay unsuccessfully.
Not sure. You would have to research. 600 became Ultegra. I found a Shimano 600 Ultegra 7 spd Uniglide Cassette. That might be what there is.
@@RJTheBikeGuy Thanks for the info RJ. My bike is vintage (1986) and has a screw on freewheel. It doesn't look like there's anything out there if I want to stay in the old 600 group set. Time for a new bike I guess.
Terrific video and well explained. I have a similar bike with a 6 speed freewheel and friction shifters (all Shimano). Can I reuse the existing parts and just upgrade the freewheel? Freewheel model # would he helpful.
If you are using friction shifters. Maybe. Whether the shifter and derailleur move far enough. Freewheel model doesn't matter as most 7 speed freewheels are spaced the same and would work.
RJ The Bike Guy
Ok I did some digging and I think I have a Shimano 105 golden arrow. I remember this was before SIS. I think later models of my bike came with 14 speed so I think there should be room for the 7 speed freewheel and I think the 105 can handle it as well?
@@19dlau69 maybe. It's friction shfiting.
I'm preparing to convert an '86 stump jumper into a touring bike. The 3x5 drivetrain is pretty shot, so I am planning to rebuild it. I'd love the option of putting a 6-speed Shimano freewheel on, particularly one with an ultra-low 34T cog. Do you foresee any challenges in going from 5 to 6 speed?
The hub spacing is likely different and you would need new shifters also. Not sure what kind of shifters you plan on adding, but road shifters are not compatible with mountain front derailleurs. And road brakes are not generally compaitble with v-brakes, etc etc.
Ok good to know that the hub spacing needs changing. That's a bit more effort than I'm willing to put in so it shall remain a 5-speed. It has Suntour friction bar shifters on it, and they still function quite well :)
Can i upgrade from 7speed freewheel threaded to 8speed threaded?
I have a 6 speed Shimano tz20 ( 14-28 )freewheel that I'd like to swap out for a 7 speed megarange (14-31) The shifter is a Shimano SIS index revo shift (grip type) The derailleur is a Shimano SIS index Tourney. Can the swap be done? What would I need to change besides the freewheel?
You would probably need a new rear derailleur that can handle a 31t freewheel, and 3x7 shifters.
Thanks for this! I have a Mongoose Hill Topper that I bought in August of 1990 at a Schwinn shop. My Mongoose has a mostly original 3x6 Shimano drivetrain and I enjoy keeping this bike rolling. Plus, the steel frame is great for my two-year old's Thule seat. Anyway, I watched this video because I'm considering whether to convert my Mongoose to a 3x7 drivetrain, or not. My thought was to use the whole 7-speed rear wheel of my wife's 2003 Trek Singletrack (she rode the Trek maybe five times total and it's essentially in mint condition with Shimano Acera components). So, if I understand this video correctly, I could potentially use my wife's 2003 Trek as a "donor bike" to achieve a 21 speed bike on my Mongoose? In other words, all I would need to do is replace the 6-speed rear wheel with the 7-speed rear wheel, replace the existing 6-speed shifter with a 7-speed shifter, and possibly use a spacer on the rear axle (if needed)? Thanks again.
Probably, yes.
If the Hill Topper has a HG FH a 7 speed cassettes might require a 130mm OLD. Easy on a steel frame ATB. I did this on a 95' Threshold. This year Mongoose had a 6 and 7 speed HG Altus group set available on HG free hubs.
How big are the gears on that seven speed in this video and how big were the gears that this bike previously had as a six speed? I am asking because if I were the one to convert a six speed to a seven speed, I would look at the sizes of my six gears before adding another one. If the sizes of my six gears, in tooth count, are 28, 24, 21, 18, 16, and 14 when converting to a seven speed, I would want that added gear to either have 32 teeth or 12 teeth, so the seven speed options that I would consider would be gear sizes 28, 24, 21, 18, 16, 14, and 12 or sizes 32, 28, 24, 21, 18, 16, and 14. Another option would be sizes 34, 28, 24, 21, 18, 16, and 14 or something very similar. If the extreme gears of a seven speed are the same sizes as the extreme gears of a six speed, then I no longer see the point of converting to a seven speen, unless if you want tighter shifting between gears.
I ordered a new 6 speed freewheel but they gave 7 speed instead by mistake. Luckily my chain works with it and all I need is a new shifter which i needed anyways
Hi RJ, thank you for all your tutorials for us home mechanics. After 8 years since its publishing this video needs a refresh. VG Sports has 11 speed 11t - 36t frewheels selling on the Internet forest. Could you do a conversion from 7s to say 10s or 11s freewheel, and what it takes for a conversion to succeed in terms of axel, derailleur, shifter??
First, a big thank you! I can't give a long response right now. I have limited internet access. When I get a chance I will give you some suggestions. I do have some videos where I go from 7 to 10 speeds. that would be the basic idea.
@RJ The Bike Guy thank you for getting back to my inquiry. I just did a conversion myself on my Hybrid bike by buying a new rear wheel with HG freehub, which costed me $85 for the wheel alone. I wonder if the product I mention could have been retrofitted to my freewheel hub with ease without forcing me to change the whole rear wheel..
Thank you again for empowering us DIYers with your insights 🙏🏻💪🏻🙂
Not really. Freewheels and freehubs are way different. Freehubs are designed to have the bearings further out to eliminate bent and broken axels from wider cog sets.
They have bigger cog set free wheels but they are not a good idea.
@@RJTheBikeGuy thank you. You're the best 👌🏻
So, my old Schwinn is currently 2x5, but I'm thinking about replacing the freewheel to add more gears. I'm not sure if I want to get a 6 or 7 speed freewheel. How much wider are the freewheels with more gears? is it really enough that you'd have to bend the frame? Also, when you say "spacer" do you mean the same thing as a washer?
A 5 speed hub is 120mm wide. A 6/7 speed hub is 126mm wide. So you will have to spread the rear triangle. But it has to be evenly spread on each side. A spacer is basically a washer. But they make them for axles in mm widths.
on those shifters, does the difference between friction and sis mean that friction would just be the old gearing-manual, without indexing option?
Some people prefer friction shifting instead of indexed shifting. So the little part on the side can be turned to select friction or SIS (indexed shifting).
thanks
Nice video, thank you! My brother gave me a Mongoose MGX DR-X 21 speed...my question is this bike good to take off-road? Is it safe? Thank you!
Not familiar with that bike, but at a glance it looks like one of the low end Mongoose bikes with a dual suspension that is more for looks than for actual use. I wouldn't take it on an serious off-road stuff. It will probably break.
Thank you....I had plan to take it off-road tomorrow...but wasn't sure if it was safe....thank you for your time. Any recommendations on a bike for off-road?
Well to start off, look for something that wasn't sold at Walmart. Look for a band name like Trek or Specialized. You aren't going to find a good dual suspension mtn bike unless you fork out some bucks. A hard tail is okay. You can maybe get a bike with front shocks. Look for good shocks like RockShox. Low end bikes may have shocks, but they aren't much more than springs and are more for looks than use. Mongoose does make some higher end bikes too, but unless you know what you are looking at, I would avoid that brand. They make a lot more low end bike that higher end ones.
shyflirt1 is it necessary to switch my derailleur & shifter if I am using friction shifting, not indexed?
You may still need to change the derailleur. It depends if the current one will reach all the cogs. Probably not the shifters.
I have been gradually watching your list of videos...great instructions and guidance. You have helped me understand the workings of my bike and how to fix and adjust several things...Thank You!!! I was wondering what advantage you will get from the additional cog in this conversion? Also, would there be greater advantage to converting from 2 to 3 chainrings in addittion to or instead of this conversion? Thanks for your help!
Hi RJ, I have a question for you. I'm trying to do a 6-7 speed conversion, and have completed all the steps, however I ran into the problem you mentioned at 1:11 - 1:27 with the freewheel rubbing against the frame. I solved this using a spacer as suggested, however it has caused another problem. Even though the wheel is completely in the dropouts, it is not central in the frame, and so is very difficult (impossible?) to get the brakes to fit properly as one pad is almost touching the rim and the other is about 2cm away. Is there a way of solving this that doesn't involve buying and fitting a new, narrower hub?
czcams.com/video/0MHBHFu4CrA/video.html
6 speed cassettes did come in HG and UG
if I have a positron derailleur instead of an SIS will it not work?
+sonomama82 I don't know if Positron went to 7 speeds.
Hi Mr. RJ, All freewheel for 16" wheel folding bike are the same thread? i ask this bcuz i also planning to change my current 6speed freewheel to 7speed freewheel. thank you
www.sheldonbrown.com/freewheels.html
@@RJTheBikeGuy thank you very much
Have you a video on how to convert these hubs to single speed freewheel? Is it even possible?
czcams.com/video/nkNCXx10NqY/video.html
Can i Use 6speed sprocket threaded? My bike is a 7speed Threaded freewheel.
Yes.
Im an avid fan of you sir..pls give me tips...my bike has a 7 speed freewheel hub...can i upgrade to 8 speed without changing my hub?
Not really. 8+ speed wheels are usually cassettes. And the hubs are wider. czcams.com/video/qcgz3-XyNkI/video.html
RJ Nice video and I am converting my foldable bike from 6 speed to 7 speed. I have found that the chain is rubbing against the screw nut holding the rear derailleur at the dropout. Is there anything I can do to fix this? Coz it’s not possible to put my chain on the lowest cog as it jams with the screw nut.
Maybe an axle spacer. I thought I mentioned that in the video.
I will try that one out. Have been watching many of your videos and fixing my bikes on my own. You really made them easy to follow.👍🏻
did you have any issues with tightness of the chain after switching to 7 speed?
Not sure what you mean by tightness. But I didn't have any issues at all.
any idea what is the name of spacer that he talking about at 1:27?
Axle spacer.
For what it's worth, Sunrace freewheels work perfect with Shimano index or friction shifters. They're ramped so they shift way better than vintage freewheels, especially with friction shifters. They look better than the modern Shimano ones like in the video with the hideous big black cog with a Shimano logo that goes on a Walmart bike, they're zinc plated and drilled and you can get them for less than $20. I have thousands of trouble free miles on them.
Hi Mr.Rj ,i have mtb with 7 speed thread type,the current cassette 14t-28t..i want to change on 9 speed 11t-32t thread type....is this possible??? there anything to change??? thank u...
The 9 speed freewheel is probably wider so would have spacing issues. With a wider freewheel you are more likely to have bent axles. And generally the freewheels above 7speed tend to be cheap junk.
hi if i have friction shifters (not indexed) do i still have to replace the shifter
harv watt no. You shift by feel.
thankyou
I am totally happy with 2x6. My problem is that I cannot get a decent hub / freewheel anymore. I don’t want to go 2x7 with cold resetting the dropouts just to be forced to friction shifting to make 2x7 freehubs somewhat work on my 2x6 SIS. I don’t understand why the big companies do not make one good retro system for those many old bikes out there. I think there are enough enthusiasts out there for a small batch production.
Did you watch the video? I didn't cold set the frame. I didn't use friction shifters. Not sure what you are talking about.
@@RJTheBikeGuy, I really like your videos! Very helpful information. In this video, you still had to change the shifter from 6 to 7, which I do not want to do, because I am happy with the quality of the Shimano 600 Series 6-speed shifter. I don't see a reason to go 7-speed. I would instead like to replace hub and freewheel with new parts (I know I can get worn/used ones, mostly for a large premium, on ebay), but I have trouble identifying a manufacturer in the SunTour quality class (Origin 8 seems to be the only 126mm option on the market and 13-XX freewheels are not longer manufactured?). In order to keep the gear ratio I am toying with the idea to upgrade the chainring from 52 to maybe 56 or even larger and then use a 14-XX freewheel.
I also got a bike that was cold set by someone to fit a 130mm 7-speed freehub, but the indexed shifters (again 6-speed Shimano 600) work only in friction mode with the 7-speed cassette. Maybe you could point me to a resource how to retrofit the shifters: It is my understanding that by exchanging one of the rings in the Shimano 600 6-speed shifters, they can be converted to 7-speed without the need of replacing the entire shifter. I am trying to find a copy of the instruction manual from the 80ies that supposedly describes the process, but so far I did not succeed.
Thanks!
Nice video. If the idea of converting a 6 to 7-speed was to get more speed out of the bike, I'm afraid the 7-speed has a 14 tooth sprocket on the smallest gear ( just like your old 6 speed). If you are going to be climbing steep hills, then it is an improvement. I just found out that by doing research there is a Shimano HG-37 7-speed freewheel has a 13 tooth sprocket on the smallest gear. Just a thought.
No, the idea was to increase the number of gearing options and make the bike slightly more modern. Going to 7 speed makes it easier to go to indexed shifting which has limited options at 6 speed. I never said it would make the bike faster.
Good informational video. Is it possible to use a Campagnolo Chorus 10 speed derailleur on an 8 speed shifter/8 speed cassette Shimano? I will replace the existing Shimano derrailleur as soon as I can get an answer from you. thanks. I click like button already and a subsciber.

I need to change the bottom bracket except for the spindle (I'll restore the spindle). I should buy new parts like a new bottom bracket, loose ball bearings, Phil Wood grease, and a new threaded locknut.
One good thing about coming aboard your Channel late..all your old videos are new to me ..
Can you also use a shimano tourney ty500 6/7 speed detailer
Yeah. Personally I would buy a good used Shimano 105, or 600, or something like. Tourney is very low end.
Thanks..hate to ask but where do you buy your used parts
Other then Ebay

Cant believe some of the questions you get ...
But anyway thanks found a gold mine
The rear dropout spacing on my bike is 130mm and currently there is a 5-speed freewheel on there. Will I be able to upgrade to a 7-speed freewheel without any problems?
Dunno. Generally 5 speed wouldn't have a 130mm spacing. So you will have to figure it out. www.sheldonbrown.com/frame-spacing.html
Yes i seems strange. The wheels on bike are 27 x 1 1/4" 32-630 if that is of any importance... Thanks for answering RJ.
Hi Mr RJ, i need your advise. I have folding bike with 6 speed. the current cassette is 14t to 28T. now i want to change only the current 14T to be 9T. is this possible? is there anything need to change? thank you and waiting for your reply.
I don't know if 9t sprocket would fit on a common cassette. I think 11 or 12 is usually the smallest.
@@RJTheBikeGuy Hi RJ, I might thinking you had experience like this. by the way thanks for replied. oh! yeah there is 9T on 3 speed cassette folding bike.
I have a 7 speed Shimano megarange MF-TZ31 freewheel and would like to replace it with this 8 speed Sunrace Freewheel13-34 MFM56.8CV0.US5.BX. I have an AL frame with 135mm span. Is it possible to just swap the freewheel without rebuilding the wheel with a different hub? If there are spacers to each side of hub can I adjust the wheel towards the non drive side with out having issues with the wheel not being centered and issues with the brakes. Right know there is a rubber boot covering the non- side spacer. I will of course change the 7 speed shifter to an 8 speed. Also I have rubber boots covering the spacers on the front axle and would like to replace them this summer when I repack the bearings. Where can I find new ones? I have looked everywhere and can not find any.
Multiple issues here. Freewheels above 7 speed are generally low end crap. Most Mtn bike wheels spaced for 135mm take a cassette a freewheel. So I don't know if you have a 130mm spaced wheel. If you have a 130mm spaced wheel, an 8 speed might not fit on it. And bad idea to use a 130mm wheel on a 135mm frame. Too many issues here, so I have no idea.
Hi, is this applicable to 3x6 speed mountain bike too?
Yes.
Hey Mr. RJ how many spacer do you put if the chain is rubbing to the side?
A 1 or 2mm spacer should be fine.
Thanks! Mr. RJ i really love your videos it hepled me everytime
You helped me everytime
