    What can I say, this is the kind of thing that either works or doesn’t. I’ve been using it for a few weeks now on road and off with a double trailer holding two little ones weighing about 55lb attached to a 907 Fat Bike. No problems at all.

    I’ll actually be ordering another one for my wife’s bike soon – the cost is worth the convenience and it lowers the risk of damaging and the wear and tear on the bike threads.

    And finally, shipping. This axle arrived at my Alaskan address in three days. Anyone that’s lived here knows that’s super fast. That means the moment they got the order, it was packed, labeled and out the door in the first thing smoking – priority!

    Fast shipping, easy to install, and perfect fit for my bike. Used the trailer for over 30 miles now and no problems.

    Perfect! I was really unsure when I ordered the axle since I know nothing about bike mechanics! I needed to pull my chariot kids carrier with a fat bike to continue to bring the kids at daycare by bike even during the winter months. It works perfectly, the design and constructions are very professional. When the roads are clear with a little bit of snow, I can easily pull my two kids weighing about 75 pounds together. And this is so much fun, way better then the car. I highly recommend this product. Really fast shipping.

    Excellent product. Fits straight onto my Haibike fat bike so I can attach a pet trailer. Easy to install – good instructions and video available online.
    Fast shipping to my overseas address here in England.

    So glad this is something that exists!! The guide for selecting the correct axle was super easy to use. The axle arrived quickly and installed easily. I’ve taken the kids for a few rides and it works flawlessly. I’ve checked the torque on both the axle and the hitch mount after riding and it appears good to go. I know it would be more expensive, but I do wish there was some sort of quick-release version. I’m not looking forward to removing the axle if I have to change the tire or do any other maintenance where removing the back wheel is necessary. I mean, it’s not that difficult to install this axle, but it’s certainly more time consuming than a quick-release.

    This place has amazing customer service. Their product knowledge has surpassed anybody else on this topic, including manufacturers and retailers. I purchased this axle and then, unprompted, was contacted to let me know I had purchased the wrong axle. This was after bringing my laptop to the bike shop to look up specs. I didn’t end up needing the axle, which saved me $75. I will be back because I plan to use my kid trailer on multiple bikes, some with thru axles. I will also recommend the Robert Axle Project to everyone I know dealing with compatibility issues. Great company!

      Thank you, Eric. We are chuckling at the comment about how manufacturers or retailers can’t even figure out what axle goes with what bike. We try our best to make sure our customers get the right product!

    I’m so glad this is now possible for fatbikes. My kids don’t ride in the chariot any more, so I use it for hauling gear on our bike camping trips. Everything was solid. The only problem I had was with the installation on my fatback rhino. It seemed that it was in between sizes. No problems though, I just hack sawed the spacer in half and filed it down. Now if fits perfectly and works great!

    Put simply, this axle is perfect. Although I purchased it to enable towing my burley trailer, I have found the axle to be stiffer than the OEM unit it replaced.

    The installation was a breeze, the packaging simple, and the instructions easy to follow.

    I have already recommended Robert Axle products to my friends, and will continue to do so.

    Thanks for a great product!

    The product was easy to size up using the axle chart. Shipment notification was quick, so was delivery was pretty good to northern Canada. Product is doing the job and all is good.

    I just recently purchased a 12mm axle for my Fat bike so I could hook up my trailer to it. I placed the order on a Friday and the axle was in my mailbox Monday! Is that fast or what? Installation was a breeze. Now my grandson and I bike around like we were meant to. Thanks for providing a great aftermarket axle that solved my problem.

    ordered one for my ‘18 trek Farley. No need to measure as it was easily chosen through drop menus.
    High quality, nicely machined part!
