FSA Chainset

Might be a stupid question thats been answered elsewhere.

I am currently running FSA compact chainset. I'll be replacing the rings this summer but have noticed that FSA sell different sized rings as well as the compact ones. They all have 110mm BCD. Does this mean that they are all suited to my chainset or do I have to have to stick with the compact rings?

    You should be able to use any 110 BCD rings though larger differences in the number of teeth between the rings tends to result in less reliable shifting. (eg 50/36=14T gap and tends to shift slightly better than 50/34=16T gap - all other things being equal including but not limited to component wear and correct adjustment of the drivechain).

    I assume shift ramps etc are the same on FSA's aftermarket rings but this would also be worth checking.

    If its a cheaper FSA one then I would bin it and start again before it falls apart on you mid way through an event.... as happened to me...:o

    FSA cranksets have a habit of falling apart - it's a well known feature they've now perhaps rolled out to the entire range. Never again!

    IME Hollowtech II has it for ease of installation and removal and robustness though I do slightly prefer Campag UT overall for narrower Q-factor, looks and lower weight

    Try telling that to Cancellara!

    I'm sure he's praying the left crank doesn't fall off every time he sprints off the front... Having a mechanic to check your bike before every ride obviously helps keep things working. And Loctite. Clearly there are plenty of FSA cranks that never go wrong but the failure rate is higher than average I'd suggest.

    Seriously though FSA cranks do have a bit of a history (my own experience, riding buddies and folk on t'internet) and since I change cranks around reasonably frequently a reliable and durable fixture is a consideration.

    The answer is plenty of Loctite 641 and 243. Never had a problem with FSA myself and have ridden the Mega exo stuff for a good few years.

    Not sure if it's the Mega Exo range only that has the history of problems or is it the ISIS stuff as well?
