  1. aduensing (verified owner) –

    Bought the steel version and put it on my bike about 2 weeks ago. It’s working well, not making noise, and not brining attention to itself. Like a bottom bracket should.

    I’ll update my review if I have any issues.

    • Power Meter City –

      Hi. Sounds good so far! Let us know if anything changes.
