  1. Eric Van Dewoestine (verified owner)

    Perfect fit for my bike.

  2. ALEXANDER MACDONALD (verified owner)

    I bought one of these for my mtn bike. The quick release style thru axle that came with the bike was getting loose all the time, so I looked online for a bolt on thru axle and found this one. I’m really glad I did, because I’ve ridden that bike many times since I got the lightning bolt on thru axle and it’s never come loose. It stays put.

  3. Ed Caldwell (verified owner)

    I received quick feedback and ordered product arrived very quickly to match my bike and axle choice. Looks great and very streamlined. Waiting to heal from broken elbow before I venture out. This was one of the upgrades I have been wanting to do for some time. Thanks to Robert axle for making this high quality product.

  4. David Barnum (verified owner)

    Fast shipping, great customer service, and a perfect fit for my bike. And they’re made in Bend, OR! I highly recommend The Robert Axle Project.

  5. Chris (verified owner)

    This was a perfect fit for my bike. It is great quality, looks clean, and no handle to bang on the rocks anymore. Their ordering system makes it so easy to get a through axle that fits properly. I would not hesitate to purchase it again.

  6. Ted P. (verified owner)

    Fits just perfect! Wonderful customer service and assistance. In conjuction I am also using the HexLox security system. Great partnership. I no longer have to carry a security cable to leash-up wheels, etc.

  7. kyle (verified owner)

    There’s no good reason axles like this aren’t OEM. So much easier to install and maintain, plus no lever hanging out to catch stuff. Highly recommended.

  8. Adam Carlson (verified owner)

    After my Maxle died the LBS suggested I try this rather than buying a new Maxle through them.
    I’m so impressed.
    Fast Delivery, perfect fit, superb performance.
    I’ve rattled down some pretty rough brake ruts, steep fresh trail, huck to flat and everything in between. The axle hasn’t shifted, loosened or caused any concerns.
    Nice work Robert Axle Project.

  9. TJM (verified owner)

    I’ve only got about 20 miles on it, but so far so good. Considerably lighter than the stock through axle and having an actual torque spec means it is consistently and repeatably installed.

  10. Mauricio Altamirano

    Perfect fit and fast delivery, even in Germany! Really high quality product and I added the Hexlox bolt lock with the metallic insert. Now my bike is protected and looks great! Btw I have a Trek Powerfly 5, 2018 Model.

  11. Brady (verified owner)

    Perfect fit, great service, and great way to clean up your axles.

  12. Daniel Finnis (verified owner)

    Fits perfectly and is so much less fiddly than the cam-over/QR style that my Checkpoint came with.

  13. John Agler (verified owner)

    Replaced my Maxle lite quick release with the Lightning Bolt. What a difference. A real quality part.

  14. Rene Ortega (verified owner)

    It works and looks so good!

  15. Davey Sprockett (verified owner)

    This axle is perfect — fits good, looks good, stays put. Love a great American made product that I can put my trust in and this is one of those. My order was shipped promptly so my Honzo was back on the trail pronto — thanks Robert Axle Project.

  16. Will P (verified owner)

    I purchased a set fork and rear and they have the exact measurement as my bike’s need.
    These are so much lighter than the quick release thru-axle that came with the bike and I do see the benefit of bolt-on as now I don’t need to worry about the lever being caught by shrubs, etc.

  17. Michael McLeod (verified owner)

    The printout provided to match the thread pitch and length is golden. It made it so much easier to purchase the right part the first time. It fit perfectly. Would not hesitate to purchase again.

  18. Max Wallner (verified owner)

    Broke my maxle after a few years…the collet system just disintegrated. Found this axle website and saw it was a little cheaper…really I don’t care much about rear axles but the replacement seems great.

  19. Cris Domantay (verified owner)

    Perfect fit for my fezzari la sal peak! Found robertaxleproject thru YouTube. Very recommended.

  20. hal (verified owner)

    perfect fit for my trek 920. fast shipping, absolutely no issues.

  21. Jeroen Swart (verified owner)

    Absolutely brilliant.

    The multitude of axles standards, lengths, thread pitches etc made it a nightmare to find the correct set of axles for my Stigmata.

    In contrast , the Robert Axle Project website made it crazy easy to identify the right axles for my bike. I was worried because it just seemed too easy to be true.

    I received them in Cape Town at the Southern tip of Africa one week later. The price was great and with shipping included the price was still cheaper than trying to source axles at my LBS or on other online sites.

    The quality is top notch. Lightweight, quality machining and top notch finishing.

    I could not be happier with my purchase.

  22. Bike Rider (verified owner)

    The Lightning Bolt axle came in at the advertised weight. I commend Robert for being honest in his marketing.

  23. Scott (verified owner)

    An absolutely perfect fit for my Turner Sultan. The original axle was beat to near death with the protruding lever catching rocks. The Robert Axle is perfect, threads in way more smoothly than the older one, and is streamlined to avoid catching trail debris. Come on… everyone carries a hex set on the trail anyhow, so who needs that extra stuff. The light weight and beautiful machining make me happy, even if not obvious once installed!
