  1. Zaxer (verified owner)

    No joke – this stem is crazy light and perfect for my gravel bike. Lighter than “lightweight” stems I was considering at a much lower price.

  2. Francois

    Ultralight stem, for a reasonable price. Nice looking.
    Easy to set-up and adjust. Nothing more to say really.

  3. Stevie Kaowabunga

    Amazing stem, I have two of these on two bikes, a 110mm x 6º on my road bike and a 70mm x 6º on my mountain bike, both flipped negative.

  4. Mark Cantrell

    Jumped over my preconceived notions – too light, too small – and got the stem with the “350” bar. Great complimentary combo, stiff, light, and compliant. Thanks for pushing the envelope in stem designs. Cheers
