This thru axle is for attaching a child or cargo trailer with a standard “hitch-style” attachment to the center of the wheel. Since 2013, we have been an important part of cyclists’ adventures all over the world. Our thru axles have millions of miles on them on mountain bikes and road bikes, gravel and cross bikes, fat bikes and e-bikes.

Your stock thru-axle is not designed to haul your precious cargo – your kids, your pet or your gear! Robert Axle Project thru axles are specifically designed to handle the heavier load of a trailer behind your bike, and are 3 to 4 times stronger than the stock axle that came with your bike. Our stainless steel axle ends provide a safe and secure attachment point of the hitch to the axle. The axle is quick to install and remove with a common 5mm hex key, allowing ease for repairs or removal.

Our axles are designed, machined and tested in the USA, by avid cyclists, to the tightest standards in the industry. We safety test, to failure, every batch of axles we produce to ensure they exceed your expectations and safety.

    Solid product, met expectations and fit my Orbea Alma Boost axle mountain bike.

  2. Daniel Arndt (verified owner)

    Nice build quality. Fits perfectly to my 2020 Orbea Laufey to pull the Thule Chariot. But the most impressiv thing was the super duper fast shipping to Germany. Thanks!

  3. Alex (verified owner)

    Finaly found an axle for my Orbea Wild HT. All good. Shipping was super fast too.

  4. Alex Wolf (verified owner)

    Just wow! Insanely fast shipping to Bavaria! With your thru axle you saved me a self-made construction. Our Thule trailer is now perfectly attached to my wife’s Orbea Wild HT.

  5. Simo (verified owner)

    Amazed how fast the product was shipped to Finland! 😀 The axle came way before the kid trailer which I ordered from a local shop. This was also the only place where I found the right thru axle for my Orbea Laufey and Thule trailer combo. 10/10 points! 😊👌🏼
