- In today's video EPIC BMX's ( / _epicbmx ) Phu Vu gives us all the information about one of the most radical changes in BMX in the last 20 years! The changing of the sprocket from 44 tooth, to 39T, 36T , 33T, 30T, 28T, 25T and even as small as 22 Tooth chainrings! This change in the gearset was one of the most impactful technological changes in recent memory!

I totally didn't understand this! Thank you for making this video! Just came across your today channel today..im stoked I found it!
I’m 44 and just got back into bmx and I was like what the hell is with these tiny sprockets lol 😂
Same here. I’m 49!
Hahaha it’s a noticeable difference for sure
Bro, we are all getting back into it at 40. Pretty sure 78% of bmx youtube videos have a guy commenting "hey im 40 and getting back into it"
I've been that guy and replied to those guys a few times.
Also, I only say bro because my kids say that 3367383743838283 times a day, so it is part of my vocabulary now. I normally don't say bro to other adults, unless I/We are mocking how stupid our children talk.
Ok thanks, bye for now.
I’m 46 and got back in to it a year ago, dusted down my mid school bike and thought if 25/9 is the norm now I guess I have to try it but I’m not happy about it, it was of course so much better and wouldn’t go back, still riding my mid school mongoose tho, it’s indestructible
You got the best videos. Thanks man!
Thanks for the reEducation of BMX broski. Useful info and chill vibes with your crew always. 😎
Great info. Love the explanation. I am building a pit bike for my son to add to his collection. This helps me a lot when I am ready to purchase the cog,chain and chainring. Thanks.
Great video 👍 I'd add, as a general rule a smaller sprocket/chainring and shorter chain will wear more quickly than a bigger drivetrain but for freestyle BMX the clearance and weight advantages far out-weigh slightly accelerated wear.
That’s a real good point Sandy!
I looove my odyssey 13t F/W, i still have it, I rode 36/13 on my #2 bike until recently. But to me, riding 25x9 or even 30x10 is way too small (23x8 is just ridiculous). I ride 32x11 on my #1 bike, and I would ride something like a 33x12 too, I think it's the perfect weight/size/wear balance. As for hitting the coping... just hop and dive in! 🤘🤘
I started on 44-16, then went to 36-13 and been at 25-9 on a freecoaster for long time now. It's great not to have to worry about the driver getting messed up in grinds being it's small and having a hub guard for it, but when I had the 44-16 and 36-13 I had the HTP(HOME TOWN PRODUCTS) dropout protector to help especially being I had the aluminum 2hip pork at the time
Remember having the GT "Compact Disc" chainwheel, with the GT logo on it, maybe a 43? Also remember hanging up on disasters terribly as well.😮😂
I used to bend 44t sprockets constantly, which would then snap my chain. This is an amazing innovation. I just wish I had a 28 or 30t fbm sprocket
I remember one of my friends running 23/8 gearing his chain where'd out quicker and went to 25/9 gearing, back in the day the gearing I went through 44/16 45/16 36/13 33/10 26/9 25/9 still on now 👍🚲💨
This video was absolutely amazing. As someone who rode BMX back in 2001-2005 I grew up on the 44T/16T. I actually ran that FBM and S&M sprocket you have on the table haha. So when I came back around BMX (I stopped riding in 2005 but still like to look at the bikes today), noticing the smaller sprockets and cogs blew my mind. It made no sense to me haha. So the video was funny, brought back memories, and was informative for us older gen guys. Just imagine having that technology back in the day with those beefy ass Haro and Standard frames haha. I've watched your other videos on the new chains and cogs/flywheels those were interesting as well. I don't remember cassettes really being a thing back in 05? I'd say probably 95% of us all used flywheels. It's honestly good to see some of these older company's still around such as S&M, Kink, and Fit. Keep these videos up please not ust to inform but for us older guys who miss the old days of riding and just enjoy the trips down memory lane. Thank you for what you're doing.
I should add do riders still not do sprocket grinds anymore? Hell back in the day we even had sprocket guards on those monstrous things haha. With them being so small is it even still possible to do?
Im still running an original haro grind disc on my 01 mira 540 air 🤣
When I raced BMX in the late 70’s, I ran a 40 / 14, a Roger Decoster frame and Redline fork.
40T must have been hard to find
@@AlfredoMancuso I don’t remember it being difficult, but that was a long time ago! I used a Takagi spider with a Ashtabula crank.
Mid 90’s I was racing ABA with 46/16 with 187.6 mm cranks. I’m 6’1 so I was cranking for speed
Good video. 👊🏼
Looking for a smooth and reliable hub set that does t break the bank. Thanks in advance for any recommendations?
dope videos 🤙🏽
Thank you!
Maybe around 2004ish I got the Standard Bash chainwheel it was 36t, that was small as hell for the time.
That was a dream sprocket 🤩
I run 28/9 and love it
44 just got my GT so much has changed from my days
I use a 44 - 13 & I love it
Godly setup
I'm only 30 and it was weird to me when I got back into it also, even though I always had Walmart bikes before. The clearance gave me the confidence to learn how to drop in, but I'm definitely gonna step up to a 28:9. I just cannot get enough speed it seems like.
I'm 13 and I run 16:44 I like it because I prefer to go fast and its better to catch up with everyone and go faster than them. and i ride a 2008 HARO Backtrail
Nice! Whatever works for you!
What current frames have clearance for a bigger gear ratio?
Back a long time ago, the best buy i made on my first bmx was the Macneil full guard 44T 😅
Is that the chain ring from pink and white gt episode that needs to be completed in a update video?
My redline came with 41/14 (2.92), I went to 39/14(2.78) to try to get close to that magical 44/16 (2.75). The mini gears might add a bit of extra stress on the chain over time, but mostly they are just ugly. One thing, with the larger gears, fine tuning is easier. going from a 44 to a 43 or 45 just tunes it slightly to you and your preferred setup. With the smaller gears, a one tooth change is an amplified change, or about equivalent to a two tooth change on the larger gear set. Maybe its a fair trade for weight, but its not for me, Ill take the big gears.
The rule of thumb when downsizing or upsizing is 3 teeth in the from and 1 tooth in the back so you’d go 22:8 then 25:9
That's why they still use them in racing
We have half link chains now for fine tuning way better then before. Especially since modern bmx frames have built in chain tensioner.
I just hated get my jeans caught mid sessions and having a rip all the way up my leg.
That was traumatizing for sure!
@@AlfredoMancuso terrible on the whitey tightey days lol
I had My Eyes on that FBM sprocket!😁😁
I run 22-9 and I love it.
25-9 for me but ive ran 30-9 and gotta say i liked the extra speed
I’m 46yrs old and been buying and building the bmx’s from my time but it makes since. I did notice the new age have the smaller sprockets but if the gear ratio is the same and lighter then it’s a win.
Exactly 🫡
What about 36t sprocket? What freewheel can we go with?
I had a newer Haro 300.1 and it was like a hamster on a wheel...
Still a fan of midschool bmx the most, heavy sturdy and fast.
Haha feels unreal to pedal so much
Good video my dude where is your shop located??
My first bmx had a 48 tooth front sprocket and a coaster brake. Early 1990s were wild
I’ve never seen one this big
Was wondering if anyone knows why my stem is making a crack noise when I push or pull on them forks are tight so nothing is moving that shouldn't thanks
What is a good gear ratio if I use a 33 tooth sprocket? On a 26 inch bike I am saying that because the wheels make a difference also
Growing up these where like pogs and slammers. We would trade,swap, buy new or used I had everything on that table. Pretty sure I still have 4 combos in a box somewhere. I always slammed into febs or bouble peg on a ledge. I slammed hard because higher then Iv done and wanted to stick it to 360 out. I broke a lot of chains and sprockets. Doing street with a dirt set up bike. We worked with what we have and had fun. Later realized a park bike was my all around bike. Just doing xups or a bar was hard with wide bars. Back then chopped bars was the answer 😂. Shorter the better until you get broke off.
That' FBM sprocket is beautiful
Yes!!
30 x 9 on my "commuter" rig, for my normal rig still on a 25x9 but contemplating on going 28x9
I was on a DK 40t for quite a while.
I'm still using a one piece crank and a 36/12 gear set... I'm this old ?! Daaaaaamn...
Haha yes
I got a 39t sprocket n 16t freewheel set up n it works alright lol
had velccro straps I put around my pants when I wore pants to ride. Usually shorts. I ran a 43 16 actually.
Oh snaps
Hey was up where you guys located I need parts for my restoration bike
Can anyone tell me info about 33/15 gear ratio? That’s what’s on my SE big ripper
What gear ratio is best for Big BMX bikes? I like 33/16, then 36/17
I remember back then, my riding buddies rode 16x22 while i was on 16x32 gearing, . We were pedaling so fast but not getting far. The richest kid in our crew has a Haro cassette hub.
Curious micro drive never caught on. Chain snapping was solved by half link chains. Was there more strength issues on the driver that i dont know of?
With the trend of frames getting shorter, i cant even go up 28t (26 and 27t sprockets are rare) without sacrificing a straight chainline.
8x25 sounds good.
Yea the tiny bearing in the driver and the stress on the half link chain still made it undesirable
I miss my 22-8. The boys and i were talking about this just the other day.
You are the Best 💕
I never had a problem with 44, and 180 mm cranks, good leverage
For the time they were great!
When I was a kid I couldn’t afford a cassette hub. So I rode a 25t to 16. 😂😂😂
Oh me and my brother @mancobra did the same 😂
Anyone with an old school bike looking for new wheels that fit, Profile BMX hubs with female axles are your answer. And Profile has custom cog sizes, not just 9 tooth. ⚙️
anyways im dealing witha pop on my bike im guessing the worn out sprockets havent brokew in with teh new chain
Or improper drive train alignment
5:06 - "I don't have a crack scale" - LOL
The clearance is a huge factor.
Did you guys ever score an 1986 GT Pro World Tour? I see performers and stuff on your channel but did you get the Pro World Tour? It's kinda rare because they got sued over the name and had to change to Pro Freestyle Tour halfway through 1986. Please find and do a video on the Pro World Tour. Thanks!
The more teeth the chain is engaged on the safer but you have to find the right size to where it's not too big that it hits everything. I personally prefer a slightly harder gear ratio so I run a 28/9 atm, I'd prefer a 30/10 though so there are more teeth engaged at both ends, I'm also running a slightly stronger than normal 510 chain because of the harder gearing.
I like this theory
That was our theory racing in the mid 90’s. Guys were toying with smaller gear but equivalent ratios for weight but the rear freewheels were the weak point. Racing is a whole different mindset to design where your drive train is the link to your holeshot off gate drop. You need your parts strong AF
Will a 44/10 work on an old school bmx with 24" wheels?
Got a ticket for running too fast in a school zone. 44/15 B.S.O. had no sense of humor. I was just going slightly over 35mph. Damn I miss the 80's. 😂
Hahahahahaha
I was born in 2000 and as a kid in a small town never heard of Bmx before and the first time I seen a Bmx bike with a tiny sprocket it tripped me out like “Wtf is that shit “😂!
I got my daughter on a 45 x 15. She can pull away on me without breaking a sweat. I run 41x16 on my 24in cruiser. Looking to get a 42 or 43 or 44 for my cruiser. I hit 25mph now wanna break speed limit on the sidewalk but we just cruise no trick stuff or clearance needed. Would love to go 25x9 but dont wanna get hub im stuck with flip flop hubs so i can run disc brake adapter.
I definitely get having a smaller one in the front but I use my BMX more for cruising around and less for tricks so I still want to be able to go fast so there's definitely a dilemma... But I'm currently driving around on the old school Mongoose from Walmart and I also have a really nice GT All Chrome all original... $$$
Lol soon as you said grab your pants leg lol oh the memories Bahahahahaha
For street/park it's great but you won't find that set up on a race track. Also, if you bent the steel one, you could probably straighten it. If you bring that aluminum to that point, it's snapping.
Solid point
We always ran aluminum on the track. Ounces equals pounds, pounds equals pain. For a while we started changing all our cromoly parts to titanium
I'm sure you can find people riding both style gears but I always thought the bigger gears come on race bikes, park/trail bikes get the smaller gears because you don't need a lot of speed in a skate park... on trails you pump to get speed where as in a race cranking may be the difference between first and second place
On a 26" bike can I run 33/16?
Mid 40's to understand? The faq? Im in my mid 30's and remember Edwin ran a 22-8 gearing. Lol
Thank Profile for bringing the cassette to bmx.
It was Shimano that introduced the cassette to BMX in 1979, but profile stuck to the concept and everyone else followed suit so your point is on point…
@@johneeeemarry34 Profile brought the one piece driver wwhich enabled 10, 9, and then 8t. Shimano always had a swapable cog, so you could never get down below 12t..
eventually i do want to switch to a smaller setup but until i get the money im happy where im at with the bike
Sounds like a plan
Good stuff. Racers still run those big gear ratios though
Good point
Smoother, ie less link movement so less friction and subtler, ie 44/16 , 45/16…
Phu the bmx gear head 🍻
Gearguys
If you think a 44 steel is bad check out a 48 Addicks
🤯
28/9 is the place to be. Bikes are nearly perfect these days. It all comes down to price point, geometry, and materials. My 26” hardtail will always be lighter than my bmx and that’s just fine.
It’s a little hard for the streets but if you ride trails or parks then it’s some awesome pedal power
upgraded my 2023 redline recon to a odyssey la guardia 28t gear. plan on using it as my dirt /trail bike. also added some weighted bars ends and all metal parts to make it feel like a speedy tank.
My 87 Detour had the same white (salad plate) sprocket 😂
Fu looks fucken hammered haha,,cheers guys from nyc
30T FTW!
my GT is 33/12 and my custom mirraco build is 25/9 to me i don't feel the difference lol
I’m still running a 52t front 22t rear, let’s just say it loves parking lots
30t t1 sprocket with a 9t
The teeth don't deform as much on the sprocket especially the driver though when I rode 28 9 the driver teeth would deform faster and look jagged and caved in.
Good point! But if you hit one sprocket stall on the bigger sprockets they would fold like origami
use the fish scale
Touché
I'm 38 I remember the bigger better cranks I feel like the smaller ones was a fad in my teenage years
give me 27 -9 , then ratio would be 3.00, 😂
Remember when the trick disaster had a meaning to it?
Ha ha ha ha yes I remember that gear it was tough when racing to get the jump on the Gate.
True many broke chains off,I remember hitting the dirt coming off a double.
Do u remember the Spider sprocket those short Alan key nuts never held to gether always loosen up & I had the that wouldn't tighten just would spinning had to try to hold the other side with a screwdriver.
Still ride my profile 44t on my custom 125r with 990 mounts. Can't take the mid school out of me. When I do a disaster at the park I hop out of it. All Gucci
Phu told me he runs 30:8 gear ratio.
He lied
@@AlfredoMancuso Phu knows who did run that set up though.
I'm 50 and still ride my old 80s redline but today I bought an early 2000s diamondback to fix up. Can I convert it to the smaller gearsets? Can I put a 9 tooth on a tuff wheels freewheel? 10:21
I always rode a 45 16. With no issues 🤣😂🤣😂
Alot of people evan my age dont know about these newer sprockets
I RUN 44 GT WINGS SPROCKET ON MY DYNO DETOUR WITH 16 ON THE WHEEL
Hehehe...😎 I'm a almost 50 year farth, I get that!👍 thanks for the video!😎👍
32/9 over here.
That’s wild
@@AlfredoMancuso I dropped down to 31/9. 32/9 was too hard and my chain alignment was way WAY off. I now run a smaller dust cap and 31T sprocket that is basically a hairline away from the frame, this having my chain alignment almost straight and aligned with the frame and ever since then, it has been so much better. And I feel I move so much faster as well, even tho it's a tooth smaller. I'm thinking about going 30/9 because where I currently live since I last left the comment, I live in Alhambra, which is a hilly type area and it's hard to pedal the 32/9 and even the 31/9.
I remember those big-ass sprockets (not to be confused with big ass-sprockets)
Hahahaha
I can't believe you guys don't have a crack scale.
30/9 makes me as fast as a car...and Tom Dugan.
I run a 33 9
I’m still using 30-11
Sprocket Taco 🌮 now I have 35 to 9
I learnt about gear ratios the hard way. My partner still had her old BMX and wanted it fixed so I went all out and painted it new parts etc. Anyway, got a good deal on new wheels, rear had a 9t driver so I got a 25t for the crank. Lo and behold with smaller gearset the chain didn't clear the brakes that were mounted on the lower rear support, so I ended up having to modify an expensive driver meant for a high end touring bicycle (really obscure ratchet size) and now it runs a cruiser 39t/14t ratio
I know you know what you need to talk about it Bmx isn’t Just Street and freestyle there’s a couple 500,000 kids in race bmx using a lot different gears from 4416 to One of my young riders is a 3915 so the the range is very big can you please explain to people Bmx is not just freestyle
Use a scale for these vids, please.
You heard PHU, send the scale and we’ll use it haha
