  1. Jeanie McClellen (verified owner) –

    Used this bottom bracket to update my 2018 Fuji road bike from bb86 to M30. Bought w the Praxis m30 crankset. Service told me it was a straight forward install. No issues and rides great.. Love my update.

    • Power Meter City –

      Thank you for sharing your experience, Jeanie! We’re glad the BB86 to M30 upgrade on your Fuji went smoothly and that our team could help confirm the setup. Enjoy the new ride feel with your Praxis crankset!
