Do FSA cranks fit a Shimano hollowtech bottom bracket?
I am looking at the possibility of getting a compact chainset that I can then switch with my standard one. is there anything else I would have to do other than use a shorter chain?

    IF you are talking Hollowtec II then yes the bearings are the same and the crankset axle will run in them. you may or may not need to use a spacer on the axle (normally provided with FSA cranks).

    Cheers, I think it is hollowtech II as it is on a bike that is only a couple of months old.
    My other Idea was to run a 36 tooth inner ring on my standard chainset to give a wider gear range.

    Can't be done on a standard chainset, Shimano will only accept a 38t ring.

    Joe. Read the original post. He wants to use an FSA compact.
    Rich. You may not need to shorten the chain if using a 36 ring. Chain length becomes critical with 50/34 and 12/27 set up. You should not need to take more than one full link out in any case. Otherwise just lower the front mech.

    John,

    In his last post he says he is thinking of running a 36 ring on his STANDARD chainset.

    OOOPS. I should take my own advice. Sorry. You are quite right.

    For some reason I thought I had read somewhere that you could go down to a 36 tooth on a standard chainset must have been mistaken. I guess if you could theyn compact chainsets would be out. what is the largest ring you can have on a compact chainset?

    I think FSA do up to 52 teeth. Stronglight do this size in Dural which is not very hard wearing. TA go to 54 but at a price. You could hit problems if you go beyond 16 teeth difference in the rings. A Shimano standard cage road mech will only take a 12/27 cassette with 16 tooth front difference. If you want more you will need a long cage. Too large a difference will also not change so well.

    TA make up to a 61 to fit on a compact. Is that big enough for you?

    If I could turn a 61 I don't think I'd need a compact... :?

    Cheers guys. Don't think I will be going for a 61 tooth. I just thought as most of my riding is round the new forest which is fairly flat I am happy with a standard chainset, it would only be if I took mi bike up to the lakes or wales then I might want a lower small ring.
