Finally getting around to replacing the stock FSA cranks with some hollowgrams on my Caad 10. I've got the Si hollowgrams with the FSA rings that were fitted to the ultrega caads in 2015. My bike is the 105, also from 2015 which I think was the final run of the caad 10s.
I need to buy an axle, do I need the 104mm or 109mm? I'm planning to use the bb that came on the bike, will that be ok and do I need extra washers or anything?
Finally old chainset is semi compact, new one is standard. Will I just need to re index the front? Do I need a longer chain. Currently my bike is completely stock.
