Square Taper Bottom Bracket To GXP Bottom Bracket Replacement
Vložit

- I show how to replace an older square taper bottom bracket with a modern SRAM Truvativ GXP (Giga X Pipe) bottom bracket. I also show how to remove and install the cranksets. This a cool upgrade/update to a vintage bike. This was part of my DIY cyclocross/gravel bike project.

I want to see how to remove it please
@@oscarpetrus666 Just watch how it is installed. Then do the opposite.
Thank u.
RJ The Bike Guy and the Park Tools tutorials are the best on CZcams.
This guy is actually excellent. His speech makes it so easy to follow the steps.
+Pak Nagasing I agree. Too many of these YT videos have poor acoustics. Can't hear half of what they're saying or droning. RJ does a very nice job.
Yup, he is good!
It's been so long since I've worked on bikes
just seeing the loosening of the crank bolts really takes me back
I think I used to open up every new or used bike I bought just to grease everything up
Good times, just bought a bike again, looking forward to the weekend to set it up!
just discovered your video and find them really practical. especially when you do the work live rather than pre-do the task as some videos do. With your videos, like the fork removal one that i watched earlier,the viewer gets a true picture of what the task involves particularly with seized in parts
thanks
Of all the bicycle channels I have found yours is the most helpful! THANK YOU!
That was fantastic. That was a really helpful step-by-step guide. I really like my local bike shop and will use it for removing and pressing in my new headset but I wanted to try this bottom bracket myself. I have the exact same job, going from square taper to external. I'm sure this would cost double for what I spent on tools. Can't wait to try. Thank you for the guide as it gave me the confidence I needed.
Thanks first for showing that it's possible, and then for showing that it's actually not that complicated. Got the old riveted together steel square taper crankset and BB replaced on my MTB with a new Deore Hollowtech II BB. Took about 45 minutes start to finish, including hunting through my toolbox.
I very rarely comment on videos, but in the midst of a bunch of confusing technical noise concerning BB's, this video made it super clear and easy to understand. Thank you so much!
Love this! Thanks for all the videos! They really demystify working on your bike(s)!
Thank you. That's really clear instruction and this is exactly what I am trying to do with my bike, replacing the square taper BB with another BB for my new crankset.
I'll be upgrading my bike's drivetrain from a MTB gearing setup to either a 1x or 2-ring road type deal with an ultimate goal of installing a Quark (spyder) power meter. FWIW, bike has a 73mm BB shell. This and other related videos of yours will be a very helpful aid if I choose to buy the necessary tools and do the work myself. Thanks so much... feeling inspired!!
Perfect tutorial. Thank you, Sir!
Great job... I really like watching all your videos, they are very helpful, thank you!
Love all your wonderful and concise videos, thanks a whole bunch.
thank you....appreciate all the hard work you put into your videos
I’m about to convert my square bb to bb52 Shimano, but I’m still looking for few tools. Thanks for the video very helpful
great video RJ THE BIKE GUY really loving your videos im doing a bicycle mechanic course in april so there giving me a lot of help
This is exactly what I needed!! Thank you a thousand times sir!
Great work RJ!
Parabéns pelo vídeo e também pela clareza da sua explicação.
This is just what I needed. thx a ton RJ.
excellent work,thank you very much and be healthy!!!
Liked and subscribed...new mtb guy!! super clear and showing all the steps...thank you!
Hey man!! The biggest thank you for you! Happy New year!!!
You're the man.... did exactly this with your guidance.
Nice real world videos thanks for posting im using this video to replace my 9 spd Sora with a 105 5800 group. Camppy crankset is nice that should be a stout a CX bike when you're done
Super. Great video work, as always!
thank you! you just answer my question on mounting a "modern" bottom bracket in an old bottom braket style bike! cheers.... whooo hooo..! haha...
I should call you RJ My Bike Guy. Thanks a lot for posting that, I can now go in my garage in peace!
God belss you RJ the Bike Guy! I could not figure out why my brand spanking new GXP BB and Apex cranckset didn't work properly, or at all even though I had followed all the manufaturer instruction regardin compatibility and installation. Removing the spacers did it.
Cheers!

@@RJTheBikeGuy Thank you! I wish I had found this video before. Or, much rather, that the manufacturer would take as much care about their instructions as do CZcams enthusiasts. Your generousity in sharing your detailed knowledge is invalubale for people like me (novis cyclist). Best wishes!
Thank you sir, Great video, I am going to use your tips tomorrow, on my mountain bike.
Excelente, tirou minhas duvidas. Aprendi.
Great information, much appreciated. 👍🚴
Awesome tutorial!
Excellent Video love your demo's
Thank you. Just excellent instruction!
Just the info I was looking for. Thanks
excellent video. helped me out a lot. thanks
Very helpful thank you
Perfect as always...
Great tutorial!! Thanks
Fantastic video, thank you so much!!!
Great Video Thamks
Easiest bottom bracket removal ever. I've had nothing bit issues with old, seized up BBs in old 90s bikes. Finally broke down and got a big impact driver from Harbor Freight to finish the job.
RJ The Bike Guy Have a question for you. Bought a 2013 Masi Uno early Spring, I want to put a new bottom bracket and crankset on. Will a SRAM Omnium BB and crankset fit?
Very informative!
Thanks mate great videos 🙏🏻
Nicely done mate
Nice, tks from brasilian guy! In 2021.
Thanks man lots of help
thank you for your effort!!
A good teacher. Thanks :-)
@rj the bike guy Shimano BB-UN-26
Cartridge Type i have this BB on my MTB now wich BB would you recommend i thought about a shimano hollowtech 2 ??
really helpful👍
Great info thanx.
Hi Rj I have new road bike steel frame only I prepare to put old bottom bracket instead new sealed bottom bracket. give me some brand & what size fit for my steel frame. Thanks
thank you so much for this vid.it can help much.
I prefer sealed bottom brackets because I think they last longer and are much smoother. Also, make sure you put a sealed BB in the correct way round. I had an idiot moment recently where it I couldn't get a sealed BB to screw into a bike frame, I eventually realised I was trying to put it in the wrong way round. lol
+john smith Not only that but square taper cranks can take the abuse of everyday riding for people like messengers & food delivery people. You can go years before changing the cranks and bottom bracket whereas with most external bb's you'll be lucky if they last 6-9 months. Sram Omniums are known for their shitty bb's. Plus I've had friends get hurt because they are riding and one of the crankarms falls off with these types of cranksets. I'll gladly choose square taper over these any day.
+dapster Sounds like some shitty install on those external BB's if crankarms are falling off. I've been running BB30 on my road and triathlon bikes with GXP on my cross bike with no problems. My triathlon bike by itself has over 3,500 miles on it and I'm still running the same BB. I do prefer ceramic bearings over steel as they're less apt to warp, but friends have been running steel bearing BB30's and GXP's for thousands of miles with no issues. If you like square taper then stick with them, hopefully nobody is going to dog on you for it as every rider has their preferences, that's the beauty of this sport.
dapster
Sam Anderson GXP's, the exact type of BB that I am talking about. 3500 miles in what period of time? I do that in about 5 weeks, not 6 months as a courier. Plus no one has ever "dogged" me for using square taper. In fact, quite the opposite (you were right. Square taper lasts so much longer than what I've been using. Why didn't I just stay using ST? Oh that's right, looks.) As far as a shitty install it's far from it. Then explain to me why I've had the same crankset and BB since 2008 - installed by the same exact shop as most of the people I know who use Omniums - and yet it seems like every 3-4 months someone I know has had problem after problem with the GXP bottom brackets such as cracking, loosening, or failing. It's not the person installing it as much as it's the product themselves.
Maximillian Chong What happened? Cat got your tongue?
thanks for the help.
You are the best ! 😉
Thank you!
Is this "new" bracket system better that the one you replaced??
That removal tool is expensive!
thanks for this video man this is very helpfull i always watching your video here in philippines 😂 thumps up bro
Lester Pandian jnwhsuhco CA crew crew CT by bio
same here from Philippines
Nice video. What do you recommend, GXP or Hollowtech bottom bracket ?
Thanks!
In my case on a Boardman Sport, the drive side crank was removed clockwise and the left side anti clockwise. Also, definitely recommend heavy duty torque wrench to remove. Luckily I have a 60" Torque wrench - would not have got it off without it.
Brian Anderson You shouldn't use torque wrenches for removing stuff.
Nice chain set
@rjthebikeguy Has anyone experianced rubbing between the BB cups & the crank on the drive side? It almost seems like there should a 1-2mm shim included.
Hello I have supercycle hooligan mountain bike with 18" frame. Could you tell me what size bottom bracket square taper I need. Thank you
Hi does the old BB have ceramic version ? Instead just want to get new crankset can I just upgraded the old BB ceramic version.?
good job
Would using an anti-seize compound like Permatex be equivalent to using bike specific grease on bike threaded fittings, such as BB retaining rings and bolts? Based on 25 years of working on cars anti-seize has been my go-to for thread treatment. Could it be that a bike isn't subject to the higher temperatures so the grease is fine, given the convenience of having it at hand? Or is there better performance (water resistance?) to the grease? And THANK YOU for the excellent videos! In the last few months I've jumped into working on my 12 year old MTB and found I really like it, with your excellent videos to guide me around the tricky stuff!
Thanks man
Good 👍👍👍
thank you
Useful tips. Requires experience
Great video. I know it’s kind of straightforward but here goes ,
What if I’m going to convert back to square taper from bb30. Any thing I should be worried about / know beforehand. B.B. shell measured 68mm
Thanks in advance
Not even sure it is possible, unless there is some sort of adapter.
thx very helpfull
Is the gxp bottom bracket still useable without the dust cover and the middle part?
Since you were using a cartridge BB, by converting to an external bearing kind, would the inherent chainline of the bike be altered? How do you fix this?
I love upgading old unique frames that are in good shape with newer technology. The guys at the bike shop like to look at me like I have 3 heads for dumping so much time and money into a frame worth $60. But if its a rare frame in good shape, why not ?? Facing, is that just for press fit cups ?
+christopher shara Do you have a reason to believe the BB shell needs faced? Was there damage to it?
No. I watched a video that said whenever retrofitting from a cartridge (JIS) type BB that the BB needs to be faced.
I have a threaded English 68 mm. I don't see the purpose of facing a threaded BB. If the cups thread in, then they would be installed properly (90°)
Yeah, a lot of stuff says face the BB shell. The tool expensive, and even my local bike shop said it really didn't need to be done unless there was some sort of damage or reason why they wouldn't be flat.
Thank you for your professional advice. I watched a 28 minute bottom bracket tutorial "Bicycle Bottom Bracket & Crankset Types Compatibility Identification Spec. Guide." Excellent, excellent info !! I'm between XTR FC M970 or FSA SL-K. The XTR's I believe are lighter. But I have SL-K bars and stem. Any suggestions ? Anni headed in the right direction ? I know it's kind of subjective. But you know more than I do.
Why is the newer style better ?? I need to change the tapered square style and wondered. Thank you for all your help !
The bearings are larger and farther apart. Less crank flex. They are also lighter.
Hi RJ. I have a road bike Specialized Allez DSW Sprint Comp 11 speed 2017. It came with a Praxis works Cranckset 52x36 and i want to replace for a Shimano 105 5800 but a friend told it is not possible, he said i have to put an adapter to use the 105 cranckset. Could you helping on this and tell me what kind of adapter i should buy?? if you want i can send pictures of the current cranck. I really thank you in advance. Happy New Year.
Hi RJ, can you tell the name of the crank arm remover you used? Thank you. Jerry

Hey I am trying to follow along with this hybrid to cyclocross build, but the videos are not numbered, have similar titles, or on a playlist together. How many videos are in this build? Could you organize them in a way to watch this bike be completed?
Hi.. some suggest that we need to get the shell faced before changing to external BB like GXP. any thought on this? I saw you just did it without facing. great video. thanks.
Most bottom brackets will be fine without facing. Facing just makes sure the two faces are parallel.
Thanks a lot. What are the realistic advantages of doing such a retrofit; as I have an old racing bicycle with an older BB than that, and I could replace it, if it is cost effectve.. Saludos de Costa Rica, Hasta la vista...
Newer cranks. Lighter. Bearings are farther out so less flex in the cranks.
I'm replacing a sealed cartridge on My eBike right now. What is the advantage of that GXP style ? What is the difference / advantage ?
I am upgrading a 1980s Motobecane with a square tape BB in a Sram GXP team English, but the drive side doesn't thread ni completely. It just threads in half way or less. The non-drive side goes in completely. Any suggestion?
May i ask the size of your frame bottom bracket? I have an old GT bike but the bottom bracket has a bigger diameter i assume its like 36 in diameter
Hi,Great vid! will there be any issues with chain angle/front and rear ring alignment with the new wider bottom bracket?
Cheers!
+Paul Jones Not really, because the chain line is about the same.
+RJ The Bike Guy
Sweet! thanks for the quick reply!
0:55-Use non-lead based 'never seize' on threads before applying pressure.
What is the diffrence between GXP and Hollowtech 2?
Can this be done on any MTB I have a [2007-2009 somewhere in that range got it used] Rocky mountain Flare MTB bike ? Want to up grade my crank and bearings to a single sprocket 11 or 12 speed.
If you have a square taper BB, you should be able to replace it with a GXP BB.
That is one old-style torque wrench. I've got a couple of those but I mainly use the click type anymore.
I own several nice clickers. But I prefer beam torque wrenches for bikes. I like them better for lower torques.
Hi I commented on another video of yours, but this is the exact set up I'm looking for.. I currently have a 1 piece crankset.. With the adapters you installed, can I achieve the GXP cranks? Thank you
I answered your other comment.
Joseph Martin, yes, and it will probably show up on another bike. I don't sell parts.
on my bike i cant take off the crank with no gears on it, i cant figure out a way to pull it off help mE!
Hi RJ I like the reviews on how to remove and replace bottom crank wheel drive and how to remove and replace the BB on all different types of BB thank you and you explain it very well and I have subscribed to your CZcams channel thanks from Mark from the UK England
Where i can get that spacer/plate with the splines
Good
