All, trying to establish if bb30 adaptor to shimano bears any stiffness issues (degradation) over bb30 set up.

Does anyone found any info online?


  • Probably as much degradation as a BB30 set up suffers.
    I'm sorry you don't believe in miracles
  • I used fsa adapter from sram bb30 on my mountain bike . Adapter bonded into place with loctite. I now have bearings I can service easily and new crankset feels no different if anything it's better.

    I tried the Praxis adapter. Creaked like mad, took it off but the BB30 back in.
  • Has anyone used the rotor adaptor?
  • I used the Wheels Manufacturing delrin (read: plastic) adaptor on my CX bike for some very sloppy muddy races.

    It was fantastic. Plastic is a good idea as it has some give to compensate for non-parallel surfaces and didn't creak at all.

    I was impressed, plus you can find them for £20.

    When i took them out they looked super knackered and scratched but that didn't impact their functioning. that's cross for you anyway.
    When a cyclist has a disagreement with a car; it's not who's right, it's who's left.
