would the 150mm or 125mm cranks be more suitablle fror trials?
what size is your wheel? for a 24 you owuld want no shorter than 150, and maybe even 170. for a 20 the ideal length is 140 or 145
for a 20" weel but unicycle.com only offers them in 150mm and 125mm
Unicycle.com has 140 mm Schwinn cranks. I don’t know how the Schwinn steel cranks compare to the Bicycle Euro steel cranks in terms of strength. I suspect the Schwinn cranks are pretty good.
140’s on a 20" trials uni is a good crank length.
