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.

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!

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!

Excellent quality and perfect fit on my Santa Cruz Chameleon with a Burley Honey Bee trailer. Super fast delivery to Finland!
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!
Tyler Porteous (verified owner) –
Works perfectly. Super simple install, and very sturdy design. Works great on my Santa Cruz Hightower LT.
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.

Top quality item! Perfect thanks for making it easy
Erik De Leon (verified owner) –
First of all, the service that I received from this company was excellent, top-of-the-heap. I was about to cancel my order since I didn’t think the item would arrive on time (shipping to Montreal). They upgraded my shipping at no charge so my item can arrive early (it was early by about 3 days before my trip). So that to me already makes this company worth the cost, in my opinion.
As for the axle itself: it was quality, fit my 2021 Specialized Diverge Carbon perfectly. The mechanic at my LBS (was in the shop for something unrelated) commented how the axle looked and felt like a quality product, so that is comforting.
Thank you again!

With the birth of our 2nd baby I needed to find a way to still get my rides in while being a somewhat productive parent. The answer was to pull my 3 year old around town in the kid trailer, but that was easier said than done since switching to a bike with thru axles. There is a lot of confusing info online as well as suspect axles, but Robert Axle Project made it easy to find the right axle I needed to make it all work! And there’s no need to remove the axle when not using the trailer, simply remove the hex nut and the trailer hitch and leave the axle in.

The website was easy to use and it found the thru axle I need for my 2021 Santa Cruz mountain bike. The thru axle came quickly and fit perfectly. I wish I found Robert axle project sooner. I was researching parts to accommodate my 148 boost rear. I called Thule, Shimmano, and to many bike shops to list with zero success. Once I entered my bike information the part I need was suggested and we have been off riding. Thanks.

Plugged my bike brand (Canyon Grizl) into the form and trusted this was the correct axle, and it was! Works great and easy to assemble if you know how to change a wheel
