Okay, I bought an ASR5 late last year and much as its great fun, every time I've ridden it I've had varying degrees of knee pain, usually left knee, sometimes both. It's been at the front, back and side of the knee, but not necessarily all at the same time.
I've read everything on the web about cycling related knee problems, tried all sorts of seat heights, angles, front/back seat positions, rested it, regular ice pack, anti-inflammatories, stretches, quad strengthening, shorter cranks etc but to no avail. I ride flats so cleat position not an issue.
Previously I had an Anthem and El Guapo and could ride either until my legs gave up, now with the ASR5 I can do an hour before the knee pain kicks in bad.
Could it be that the bike simply does not suit me? Anyone had anything similar? Was wondering if the slightly wider back end (142) meant I can't get my feet in the right position coz the chain stays are in the way? Feel like I'm clutching at straws though
