probably easier than finding a 29t ring in 104bcd...
Hadn't got as far as actually looking for parts yet, but the crankset is threaded for a smaller ring at the back - hopefully I can find something in whatever bcd that is. 21t would be for lower gear, but thanks for the offer
If you want to borrow a 21t cog lemme know. 32:21 is same GI as 29:19 (40") and probably easier than finding a 29t ring in 104bcd...
Edit: oh, unless this is for lower gear dingle purposes...
