Hi, I have specialized mworks 95 full campag record, I would like to look at upgrading the chainset. Two reasons the cassette range is tight and I live amongst many large hills and I recently noticed that the rh crank clearly had a problem at one stage and was replaced with a shimano. I can see I can get campag 8 speed cassette still, will it fit easily with the older hubs? Hopefully enough detail to get some form of answer?
