    My friends just bought a spesh transition time trial bike frame (new 2013) and has a spesh time trial doner bike. His current one has a fsa gxp chainset but the new frame is bb30. Is there such a kit to convert from pf to threaded and are they any good and reliable? Only it will get a hammering as he competes.

    Thanks.

    Edit: only I got the job of building it.

    Wheels manafactureing do press in converters
    To adapt press fit to most things.
    That fsa one is prob not gxp as that’s for SRAM

    Best one I’ve used is the praxis works converter bb

    I know it says shimano cranks only but a lot of fsa use the same 24 mm axle dia
    BUT I’ve never tried it so do more asking

    i second the praxis works but as mentioned above, if he’s running an fsa chainset he won’t be running a gxp bb. fsa have a million and one bb’s to suit their chainsets

    Time trial stuff doesnt get a hammering its not usually used that much and ridden on smooth roads at a constant cadence

    He said (and he wrote it down so I couldn’t get it wrong) gxp – fsa- aero (which I believe is a carbon jobbie) 52-48…

    No good for my mtb. 😉 I’d smash it of the first rock I saw!

    But saying that he could be wrong. I’ll inform him then. He’ll be a happy bunny.

    Thanks for your replies guys. 🙂 I know what I’m doing the weekend. I’ll post a pic of the finished item.

    I just had a read on praxis and they have their own bearings in. he wants to use his ceramic ones tho. I think I need better info And looked at it myself before posting.

    the sram pressfit30 to bsa threaded adapters will work best for him then.
