best gear for rollback
- Thread starter ÃX
- Start date
I think I'm going to change me STP to SS. I'm going to try a 36t x 18t. 2-1 gear ratio.
I'm running 25/12=2.083:1. Little tougher than 2:1, but not too hard. I like it.
25:10
26/12 or 2.166:1
32-16 nukkas
36-16 2.25:1 on 24s. mello enough for rollbacks but it's tough to get enough torque through to lock the rear to half cab w/out a brake.
Yup, I run a 25/10 on 24's too.
32:11, but I like not spinning out... ha
34-16 on the 26".
on a 20" bmx, i grew up on a 44/16. that's what everyone rode for years until the small cog trend. 33/12 is exactly the same gear:
44/16=2.75 X wheel size of 20" = 55
33/12=2.75 X wheel size of 20" = 55
that's why i run 34/16 on a 26":
34/16=2.125 X wheel size of 26" = 55.25
28/13=2.15 X wheel size of 26" = 56
If you're getting close to 55, then that's a good all-around gear for a single speed bike. Flat ground and street riding maybe you want to go faster. Trail riding with lots of steep climbs, maybe something spinnier.

2:1 is for skirts and fairies.
30-13.... 2.31:1
30-13.... 2.31:1
Have used 23-10 and 25/26 -11, just switched to 30-13... via a Solid BMX front chainwheel, Profile cog, and KMC 710...
36:16, that's a 2.25:1 ratio on 26"ers.
Perfect for a fast BMX track/dirt yumps.
Works out to ~2.93:1 in 20" terms (which I think in).
The standard 44:16 works out to 2.75.

im running 36:16 soon to be 25:10 or 26:11
out of the 20 people posting in here...i doubt they can all do rollbacks, and i doubt their gearing makes that much of a huge difference.
i have 26/10-on my bmx...and im just learning 180s now...im just having trouble peddling one momment, then pedaling backwards the next...i lose my balance

Roll backs. . . like rolling out of fakie, right?
I've noticed a recent trend in bmx videos of people actually hopping out of fakie. It looks a little sketch, but I guess it could be fun. Personally, on my 20", I favored no specific gearing for the trick. I used to run36-16 (spinny for a bmx bike) and now I'm on 36-13. You don't really need that much pressure to spin out of fakie, as most of the stopping/turning motion comes from the turn.
Sama1ter -- it always helped for me to find something fixed to look at and then spin the pedals faster than I should. That way when I'm rolling out, I'm rolling back at the speed the bike needs to move and I don't have to worry about dealing with any strange feedback from the pedals.

32:17 here...
I can do them. Try doing roll backs out of 1/4's or in mini pipes and then link them when youre landing 180s clean. Im now over rotating my 180s to around 270 or so and then flying out the front wheel for the 3. Im still dying to get flat clean 3s, but it aint easyout of the 20 people posting in here...i doubt they can all do rollbacks, and i doubt their gearing makes that much of a huge difference.

Im going to drop my 25t to a 23t to see how a little more crank pressure will effect things.
