Re: problems with driveshafts
Depends on what your limiting factor is. If it's clearance with other components, make it as large OD as there is room for, and then as thick-walled as you can get.
If you're worried about weight, larger thin-wall is stronger pound for pound (and probably dollar for dollar)than smaller thick-wall, until the wall gets so thin that it's susceptible to impact damage.
FWIW, the driveshaft is a cheap, easy-to-replace fuse in the system. Better to break it than a hub, axel joint or differential.
Maybe you need a spacer under the skinny pedal. [img]images/graemlins/smile.gif[/img]
