    I had a problem (not being able to use my new bike trailer) and the Robert Axle Project 12mm thru axle for kid’s trailer was the perfect solution! I have now put this thing to the test on several rides with my son and it’s held up extremely well. You know something’s good when you can just forget about it.

    Works great, and only took a few minutes to install. Very pleased with the purchase.

    The Thule brand adapter wouldn’t work for me so I reached out. The Robert axle works perfect and shipped quickly. Thank you very much.

    This worked perfectly for my Niner RLT 9 hooked to a Giant kid trailer! I pulled my four year old along on his first bikepacking adventure. An over-nighter to a Michigan state park campground. 35 mile round trip and no issues whatsoever (other than a few potty emergencies and cries of “are we there yet” from the back). Looking forward to our next adventure!

    Easy to install and it works great. I was a little worried that it wouldnt be strong enough for the trailer. But after heavy use for about a month its going on strong.

    Easy to find the axle you need. Easy to order it. They even sent it to New Zealand. Nothing I can think of could have been done better.

    Best thing ever! Great quality construction and drop in fit.

    So I use my new Norco Torrent (with thru axles) hauling a trailer as a side gig delivering just under 100 daily papers around the neighbourhood.
    I love the job and my new “Robert Axle” is just the ticket required. I no longer think about the approximately 75 lbs I’m hauling and how it may effect both my cargo trailer or my axle. It just works.

    Glad to be back on the bike and a new version of freedom!

    Perfect! Allowed me to hook my pet trailer up to my 2017 Haibike Sduro. Now I use it for all kinds of things- trip to the hardware store? No prob. Groceries? Yup. Nice work.

    Took no time at all to find the correct Axle for trailer which mount. I have a Fuji and a Trek Bikes needed ban axle for each so I could use my trailer for grocery hauling or camping. They have the perfect axle for each bike. they made it easy and quick to get what I needed. Only took a few minutes to change out my axles. Wish buying parts was this easy all the time.

    Passer perfekt på min Haibike. God kvalitet. Kjapp levering.
    Perfect for my Haibike. Good quality. Fast delivery(to Norway).

    Works perfectly. I am able to pull our chariot trailer with my TA bike. The axle finder is a good tool. Overall a great product at a reasonable price.

  16. Richard Blankenship (verified owner)

    As with all thru axles I have purchased for use with my Trek Domane, they have all been and worked excellently. This thru axle was no exception. Very pleased with the quality of the product and the service from the group.

    Shipped fast. Fit perfect. Keeps that trailer rolling.

  18. Brycen Rackham (verified owner)

    I was kind of skeptical at first, especially for almost $60. However I am very satisfied with the quality and it works like a charm!

  19. AA (verified owner)

    Got what I paid for.

  20. Nicholas Ludwig (verified owner)

    Needed something that would hook a burly bee up to my salsa. This axle works great so far.

  21. Jeremy (verified owner)

    Works exactly as expected and seems like a quality product. No hassles replacing my existing axle and mounting the chariot hitch. Delivery was also quicker than expected.

  22. Jacob Loehr (verified owner)

    Awesome product. I purchased a kona bike and a trailer to haul my 15 month old around in but I didn’t realize that the trailer wouldn’t hook up to the bike. A guy that works for life cycle bikes in Eugene where I got my bike told me about the Robert axle project and that they could help
    Me out. I sent an email in and they responded very quickly and got me exactly what I needed. The service was great and the product was second to none the machining and quality blew me away. Super easy parts swap out, took maybe 5 min. And now we ride daily. Would highly recommend this to anyone, and I have to a bunch of people already.

  23. Audun Føyen (verified owner)

    Easy to find right axle, very good explanations on the website. Good instructions included. Shipped very quickly! Got it to Norway in a matter of days. Solid craftsmanship. Brilliant! Highly recommended!

  24. Sean Farrell (verified owner)

    This is a phenomenal product! I am finally able to pull my daughter’s trailer with my 2020 Salsa Timberjack. The tool for product for checking was easy to use and gave me confidence that I was buying the right axle. The fit and finish is terrific, and it has brought hours upon hours of joy to my family. Thank you!

  25. Matt Demers (verified owner)

    Fantastic product. I was told about these axles by a local bike expert as I couldn’t hook our chariot trailer to my Kona. The product is really well made and arrived quickly to Canada. Install was five minutes. Thanks for making good products and having excellent service.

    Five Stars, one for each: works great, fair price, easy install, quick shipping, product for my bike/trailer combo.

    Works great and the quality makes me feel comfortable when pulling the kids around. A huge variety of parts ensures that you’ll be able to find what you need for your bike/trailer combo (which can’t be said about the other big names out there!).

    Thanks for looking after us and keeping us rolling!

    Needed this axle for Trek ALR gravel bikes used to tow a Thule baby trailer. Could not find this axle adapter anywhere locally. Robert Axle’s website directed me immediately to the correct axle, and they had it in stock, it was an easy installation, and it fit perfectly!! My biggest rave is the customer service I received. They called my on the phone to answer questions I had, put the axle in the mail immediately, confirmed shipping, and I received it two days later. Their prompt service saved a planned expedition out with the new trailer.

    Exactly as expected with excellent quality.
