I've just bought a second-hand road bike to replace a stolen one, but
I've now noticed that the LH crank has a crack running right across
the eye at the BB end. I can hear it creaking, so I think it may give
up sooner rather than later. The chainset is Campagnolo Avanti, about
10 years old. Since I bought the whole bike for £100, I need to
replace the crank equally cheaply otherwise I've wasted my money. It
doesn't need to be perfect, it just needs not to dump me in the road.
I imagine getting a genuine spare is out of the question, but from
what I've read most of the incompatibilities in chainsets should only
affect the RH crank. I'm hoping that I can get away with replacing
just the LH one with a random part off ebay. It looks like I pretty
much just need one the same length (170mm), with the same fitting
(square taper). Does that seem reasonable or am I being over-
optimistic?
Thanks
