    Now I can peacefully wait for coming winter, because the trailer were earlier attached only to my race bike, which is not ideal bike on winter time 😉

    My bike: Radon ZR Race 8.0 27,5″, model 2016.

    I will definetly tell about my experience to all my friends and local bike dealers!

    Works like a charm! I was a bit skeptical at first given the name of the site but then I really needed a solution for my bike. The price is a bit high and I missed a discount but the folks at Robert Axle Project was great enough to credit me back the discount.

    The product worked as advertised and I am back in towing my girls around once again! Thank you so much for having this product!

    Great solution for thru axle bikes. I purchased a Specialized Sequoia and needed to pull Thule Chariot trailer. I tried Thule’s axle first, but the thread pitch didn’t match. The Robert Axle Project fit perfectly, accepts the Chariot hitch receiver easily and is a much better option than frame mounted devices.

    Fits perfect for my Specialized Turbo S, the car stays now in the garage when bringing the kids to the kindergarden.
    Shipping was also quite fast.

    Thank you!!!!!!when i upgraded to a new bike i didn’t consider if my $400 Burley tail wagon would work. i went from a quick release skewer to thru axles. and of course it didn’t. Thank goodness for this product it saved me a ton of money and aggravation. And my puppy thanks you too….

    A pleasure to be the 10th reviewer! Prompt delivery of my thru axle to keep my new specialised diverge towing our 1yr old in the Thule chariot. Feels quality and solid and had there been any problems Im very confident TRA would have assisted. Arrived in Australia very quick too. Easy to fit and set up. Just make sure it threads right through the frame at the other side so it’s flush. Thank you for sharing your passion and minimising disruption to our favourite hobby!

    Works great on my Specialized Diverge with an Aosom Elite II trailer

    Excellent solution for kid trailer + thru axle gravel bike. The instructions for measurement & part selection are accurate and thorough, and I received prompt and clear answer to an inquiry that I made before placing my order. The system design is elegant, and installation was very straightforward using the online video as guidance. I will likely be ordering an identical item for my spouse’s next bike.
    Thank you, Robert Axle Project!

    brilliant! Nobody could help me – except for The Robert Axle Project! Surprisingly simple and fast product finder! Thanks!

  18. Árni Þór Eiríksson (verified owner)

    Exactly as Id imagine…12mm axle made of quality materials, perfect fit for my Santa Cruz Chameleon 27.5+ bike. Detailed enough instructions and fitting the trailer Was easy. Will definatly recomend.

    The product finder is very easy to use and seems to be accurate

    Excellent quality and perfect fit on my Santa Cruz Chameleon with a Burley Honey Bee trailer. Super fast delivery to Finland!

  20. Turbotime4 (verified owner)

    Top notch quality product and very easy to install – I did find it hard to torque the outer nut to spec given that you have to hold the axle while tightening but the ol german gutentight has seemed to do the trick. My daughter loves being pulled in her trailer and I like that I can now use my Santa Cruz Chameleon on and off the trail!

  21. Tyler Porteous (verified owner)

    Works perfectly. Super simple install, and very sturdy design. Works great on my Santa Cruz Hightower LT.

  22. Gabriel (verified owner)

    Light weight, easy to setup, and works like a charm. I love that you set it up once and then swap between the standard axle and this one in seconds without requiring further adjustment. Brilliant and effective.
