I like the biopace on my fixed gear.
Haven’t had any problems. I wouldn’t mind trying other sizes.
It’s a 46, a 42 would be cool, I could put it on the same bike. It has a Dingle in the back, so it would be totally messed up!
A fixed gear touring bike, running biopace with 2 gears, on 700cx 35 tires.
If you count the other side of the hub, I guess there are 4.
There is a two speed BMX freewheel over there. So I have 42-46 chainrings.
A 17-21 Dingle. And a 16/ 20 freewheel. I can ride just about anywhere I want.
