I've been searching for a jackshaft, and the only pre-made ones i have been able to find are the ones from sickbikeparts.com. However! $200+ sounds extreme for such a simple small part! I have found many threads of people building their own, however none seem specific enough to really get my head around what is needed. Can anyone point me towards a thread or link of a specific and simple build? or does anyone know of an alternative jackshaft that is less than 200? Thanks!
