    Been working great. Fit perfectly.

    The Crankset was delivered promptly and was exactly as described on the website. it's been working perfectly fine on my Canyon Dude with the other SRAM Equipment I picked up to upgrade the entire bike to a SRAM Electronic Drivetrain.

    I have had some issues with technical climbs, was told my free hub was part of my issue. Didn’t have money for a wheel set up grade, but this new ibis free hub for 69$ was a great compromise. Install was straight forward, thanks to many YouTube videos. I noticed a big difference immediately.
    I buy from thunder mountain because it is not a variable,I can count on them.

    Wanted to go up to 203 on the rotors - that was the right choice - and these were the right choice. So easy. Should have done it sooner.
