My Onza does this, as does my DMR dirt jump bike. Does anyone have any idea why it does this? It doesn't do it all the time though. I noticed it when walking to the park with my girlfriend the other day and my peddle struck my calf!
My Onza has a forward freewheel. It peddles smoothly and doesn't seem stiff anywhere, and the chain isn't over tensioned, (has about 5mm play in both directions at the tightest point). Not so much a problem, just a query. Has anyone else encountered this?
