Description

Since 2013, we have been an important part of cyclists’ adventures all over the world. Our axles have millions of miles on them in mountain bikes and road bikes, carbon bikes, fat bikes and e-bikes. Our axles are specifically designed to handle the high-torque loads generated by e-bikes.

Your stock thru-axle is not strong enough to haul your precious cargo! Our axles 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.

Our axles are not just designed in the USA, but are made here as well. They are machined 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.

 

Specification

Robert Axle for Hitch-Mount Trailers replaces your stock axle to attach your child trailer to your 12mm thru-axle equipped bike.

  • This axle is compatible with Burley, Carry Freedom, Chariot/Thule, Croozer, Instep, and many more.
  • The true length of the axle shaft is 167mm, but can be shorted using the included spacers – a flat spacer and a tapered X-12 spacer. This allows for axle lengths of 152 mm or 167 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 142mm long axle.
  • This axle has a 1.0 mm thread pitch.
  • The axle shaft and axle end are precision CNC machined.
  • The axle shaft is 7075 aluminum and hard black anodized for rugged durability.
  • The axle end is stainless steel, which allow for mounting of the hitch provided with your trailer. The threads are M10x1 (metric).
  • Hardware for attachment of the hitch is included; the hitch is not.
  • No special tools required. Design allows for installation or wheel removal using your standard 5mm hex wrench.
  • Designed, built and quality tested in the USA. Proven around the world.

    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….

  9. Jeff (verified owner)

    Good quality, works well, perfect fit for my bike.

  10. Chris (verified owner)

    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

  12. Andrew (verified owner)

    This worked great to attach my Hamax Outback trailer to my Santa Cruz Tallboy 1. My daughter loves it!

  13. Andrew (verified owner)

    Easy to use. Great product and customer service. I’d highly recommend it.

    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!
