    Robert Axle Project had a hard to find axle size at a great price and made with exceptional quality. I’ve recommended TRAP to multiple friends.

  2. raymond bellefeuille (verified owner)

    wonderful product,great support, looks great, and performs even better.

  3. Jonathan Zappala (verified owner)

    This fit my 2016 Trek Stache 5 with a rigid fork. I love how much better it looks. My old axel with a quick release cam head weight 83g and this one weighed 51g. Torqueing it to 12Nm also is feels satisfying! I bought from them because of reasonable prices and fit guarantees.

  4. Miles (verified owner)

    It’s light and it holds my front wheel on extremely well. What more could I ask for?

  5. Frank Velasquez

    Lightweight and they nailed the fit for my fork. Thanks guys!

  6. Hans (verified owner)

    The axle worked perfect. Full stars for speedy delivery and communication!

  7. Scott (verified owner)

    Super-light, beautifully machined, and threads so smoothly. I took this axle out for the first time today and found that it had not budged after tons of big hits, so that locking lever on the original really does nothing after all! I loved the Axle Finder as it had the correct options for my 10-yr old bike.
