    'Wheels Manufacturing' make a conversion kit for less then £15 which will do the job. Just type it into Google and your choice is endless.
    Society is like a stew. You have to stir things up now and again otherwise the scum will rise to the top.

    I went the cheap route initially and it was complete sh*te - bought form Merlin, cant remember the exact brand. Only had to look at a hill and it worked its way loose.

    Ended up using the Praxis one and it has been faultless since. Approx 1500 hilly miles plus Paris Roubaix, rain and sunshine...well the sun has shone briefly.

    Fingers crossed as I may have just given it the kiss of death arrgh.

    Praxis or KCNC - anything that uses the original BB30 bearings is not going to last very long as it's a $hit design
    Make mine an Italian, with Campagnolo on the side..

    The best i've used is a complete bb not a converter.
    It's an american bb made by Hawk racing, just search on youtube for some of there videos.
    If you email them, they will send you the email to the supplier in the UK.
    I think a BB30 to 24mm bb is around £70, not cheap but it's top stuff.

    All, I currently run an F4 Felt with BB30 bottom bracket with the cup adaptors and an Ultegra crankset - as supplied standard on the bike.
    I've been having some creaking noises which have been hard to track down. I've regreased BB30 bearings & cup adators, removed, greased and re-torqued chain ring bolts, and removed, greased and re-torqued pedals. This seems to have worked, but I have heard numerous horror stories of creaking BB30's.
    If I eventually decide to convert to something like this, I presume the bearings pressed into the BB need to be removed to fit this Praxis adaptor. Is that correct?

    Thanks,
    D

    Never mind - just read the installation instructions linked from the original link.

    Seems a nice solution.

    My LBS fitted it but essentially yes. The Praxis is a complete BB in itself so all the BB30 components are removed, its good so far. My gut feeling tho is its only a matter of time, the last type of BB I didn't have issues with was a square taper one. Since I moved on from that I've needed to have the bearings greased regularly. Bottom brackets are a pain in the a**e :twisted:
