  • Praxis BB for M30 cranks in BSA shells.
    Upgrade SRP £35. Everywhere lists it for £50+, claiming RRP £60.
    Did the product change recently or something?

    Assumed M30 would be like GXP and bought a "DMR AXE M30 BSA BB" from CRC for £31. Arrived in a Praxis box with a "DMR AXE etc etc" sticker over the Praxis part info and barcode. Turns out, DMR AXE cranks has a removable driveside, like RaceFace X-type chainsets, whereas my Praxis Turn Zayante M30 cranks have a removable NDS crank, like Shimano HT2.

    The bearing's the same on both sides, but there's a 2mm thick sleeve pressed into the bearing on one side. The wrong side.

    Option 1: Press out sleeve from right bearing and press it into the left bearing.

    Option 2: push both bearings out of their cups and swap them over.

    Option 3: remove both bearings, press out the sleeve, buy shiny new bearings, press sleeve into new left bearing, fit new bearings to cups.

    Option 4: return to CRC and hope they don't mind the damaged box and sticker, buy normal M30 BSA bb from somewhere else for too much money

    Help?

  • I read that twice and still didnt understand .. I have praxis with M30 that I installed last week ..

  • You remember one side has a smaller hole than the other side because the 30mm axle steps down to 28mm?

    I bought a BB that CRC said would fit, but it won't because Praxis cranks have their splines on the left side, DMR cranks have their splines on the right side.
