Heylo,
I really need to the crankset on the trike to something short. 160/165 instead of 175 in the hope that it stops my knees hurting when riding it.
Crankset is a FSA Gossaser triple, and the bb is a FSA mega exo. Trike is a Challenge Concept XT.
What cranksets and bbs are directly exchangable with the currrent system?
