This is a thru axle to attach trailers to Mavic Speed Release bikes. 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, from all over the world.

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.

Robert Axle for Kid Trailers replaces your stock thru-axle so you can attach a child or cargo trailer to your 12 mm thru axle equipped bike.

  • This axle is compatible with Burley, Carry Freedom, Chariot/Thule, Croozer, Instep, and many more hitch style trailers.
  • The true length of the axle shaft is 165 mm. Please note: Thru-axle lengths do not equal hub standards. An axle has to be longer than the hub to fit in the frame. A 12×142 hub does not equal a 142 mm long axle.

    Fast delivery. Well made and can’t even tell the difference between my true axle and this one.

  5. Lukas (verified owner)

    Perfect fit. Fast shipping (Switzerland). Axle finder helped identifying the right model easily.

  6. Todd (verified owner)

    Great product. Worked as it should. Seemed to be built from quality materials and is working flawlessly. I found the price to be high although similar products from other manufacturers were similarly priced. Axle finder was huge help. I would recommend.

  7. David Franklin (verified owner)

    Great! The axle fitted perfectly. Living in Sweden, ordered on Tuesday and got it on Friday. That’s about as fast as it gets!!! A really good experience shopping at Robertaxleproject!

  8. Andreas Westling (verified owner)

    After spending weeks trying to find a fitting axle here in Sweden, buying the wrong one twice I stumbled on this site. Super easy to use the axle finder and felt safe with the fitting guarantee. It arrived only a few days later, was cheaper than the one I’d bought in Sweden and fitted perfectly. Strongly recommend anyone to buy this or any other product from here

  9. Martin (verified owner)

    Great Product – good quality, fits as promised. After being consulted for a wrong axle in a bike shop, I gave up and lived with an “ok” solution. Never made me really happy though. The axle finder made it easy to find the right piece and I had it in my hands 3 days after I placed the order. It fits great and pulling the trailor like this feels very safe.

    Amazingly fast responses and delivery!!
