Is my bike too small??
Earlier this year I bought a brand new (but 2006-frame) Condor Leggero and in many ways it's a brilliant bike. But I've had back problems with it ever since. My lower back hurts - sometimes more, sometimes less - after about 20 miles or so and it's really made me a worse cyclist. I'm much more comfortable on my old Langster which is a real shame as the Condor cost a hell of a lot of money.
I'm about 5'9" and it's a 52cm frame. I've tried making every adjustment possible but none seems to make much difference. The Langster is 54cm.
Has anyone else had a similar experience? Is my bike too small or is there something I can do to be able to cycle proper distances again?? Anyone had lower back pain that they've got over (without getting a new bike)?
