I recently bought a revolution cross 1 and after a week I've bent the middle chain ring quite badly and the outer one a bit, I think by spitting a big rock out from the front wheel and unfortunately it then smacked right into the crankset.
I was a bit surprised (my own fault for not checking) to find that the chain rings are riveted and so I now have to buy a new crankset. I've looked around for other square taper BB cranksets with removable chain rings, but what look like higher quality components say they are for 8/9/10 speed cassettes and I have a 7 speed freewheel.
I'd like something that will not bend on contact with a rock ;) Failing that something I can swap out the chain rings on without buying the whole shebang.
Thanks in advance,
