On the powerstroke, my quads are rubbing my seat stays real close to where the meet the seat tube. Seems to happen most often on the ride home right after working out, but it's still annoying. I am trying to figure out if it is just me being a freak, or if this happens to anyone else. Near as I can tell, everything is setup well, frame fits me, seat is at proper height/angle, bars are comfy, knees don't wobble back and forth.
I can't imagine it would have anything to do with the stays being wide, rear is spaced at about 124mm. Frame is an old Dave Scott Ironman.
Posting here, because I haven't had this happen on any bike other than my conversion.
