    Great bit of kit. Works perfectly allowing me to tow our Croozer Kid for 2 trailer with my Shimano 142x12mm E-thru axle equipped hardtail (2016 Genesis High Latitude). Very easy to work out which axle I needed using the sizing guide to identify thread pitch and length needed. Early days as I’ve only used it for one big ride, but very easy to fit. I only intend fitting it when I’ll be towing the trailer as it does stick out quite a bit from the frame but that’s not a criticism (any axle attachment will be the same). It’s not cheap but it IS good value given the design input and high quality of the product. Unfortunately UK customs intercepted it and applied a GBP£11 import charge but that’s just your luck. Thanks.

    This is a brilliant product, both highly durable and perfectly designed. I had it installed on my Curry Tech E3 Dash in under 10 minutes, and felt secure knowing my Allen Sports two kid trailer was firmly attached. The axle selection and installation processes were really simple you guys. Nice job!

    Worked great for burley trailer on my Raleigh Stuntman. Customer service answered questions quickly before ordering. Very well built.

    Works great. Have a Jamis Renegade Expert (2017) – using this to tow a burley d’lite.

    Wonderfull solution: perfect fit (with selection tool on-line), high quality, handy solution for fast replacement with original axle without removing the kid trailer kit from the axle.
    I use it for Thule Chariot Cx 1 and 2 on a cyclocross bike. This is the best choice you can make as even Thule’s one didn’t fit well. The Robert axle one is the perfect customized solution.

    Exactly what I was looking for!

    I recently purchased a new bike with disc brakes and threw axels and could not find a way to attach my child’s wagon without damaging the carbon frame.

    The product is designed and built very well and is easy use and swap back and forth with the stock axel. I would certainly purchase this again and would recommend to anyone looking for a secondary axel that is very reasonably priced. Instructions were very easy to follow I had zero issues with the install or use.

    When my Project Hero Sponsors proposed upgrading my 2007 Cannondale Optimo 3 with a 2017 SCOTT Solace 10 Disk, my chief concern was finding a through axle attachment to still tow my children in the Allen Sport XLT-X2 Trailer. The product sent by Robert Axle is stronger than my stock axle, has the exact same thread pitch, came with detailed installation instructions, and worked perfectly, while not damaging my carbon framed bike. Definitely worth the investment.

    Bought through the UK supplier SJS Cycles. I spent a long time researching the right Thru Axel for my Vitus Substance V2 gravel bike (available online through Chain Reaction Cycles). I downloaded the size guide and checked thread size. I was nervous the axle wouldn’t fit – but it fits perfectly. Looking closely at the product you can see it has been very precisely milled and the finish is very high quality. Have to say £55 for an axle is fairly expensive but as you guys are the only manufacturer of this type of bespoke product I was prepared to spend the money to get the right product for safe travel with by children’s trailer. Keep up the good work. Might buy the t-shirt next. Happy riding.

    This just works, Simple process, and a simple axle that works and fits my bike. Not much more to say! if you need a 12x axle for a kid trailer just buy one and it will work.

    This gets the highest praise for something like a thru-axle — you don’t even think about it. Allows me to attach the hitch cup for my Thule Chariot trailer with no penalty in functionality or weight. Towing a Chariot Lite behind an aluminum gravel bike, for reference.

    Excellent purchase, got this for my Rocky Mountain Solo 2018. Fit was prefect and customer service was top class. Keep doing what your doing guys.

    This has worked great on my Kona. Simple to install and worked great for my equipment. So glad i found this and can enjoy bike rides with my kidos!

    Burley did not offer a thru axle for my 2019 Kona Sutra LTD and pointed me to Robert Axle. It fits great and works well.

  14. George L (verified owner)

    Exactly what I needed. I got a Burley Bee trailer to haul my dog around in, and since I already had Robert Axle Project axles, this was a perfect drop-in replacement.

  15. Simon Kurtz (verified owner)

    I replaced the axle on my 2019 Kona Sutra to pull an Instep Take 2 Kids trailer, and it worked perfectly. Take note that if you connect that trailer, the tab doesn’t have a place to fit like you would on a dropout. The craftsmanship on the axle was superb. The printout to identify the current axle to determine its replacement worked very well as well. Thank you for those easy steps.

    An improvement that I think could be made would be to supply to smaller washers rather than one large one. As it stands, the axle’s threads extend just a couple millimeters, but that’s not a functional problem whatsoever.

    The shipment was processed the same day I ordered and arrived very quickly. Thank you so much for that as I was in a bind to get it quickly prior to an upcoming trip. It’s now been road-tested and performed flawlessly.

    Works perfectly for my Kona Rove NRB 2020 with Thule Cheetah. Shipped fast overseas to Finland.

    This axle was a god send for us. We purchased a Chariot Chinook then decided to buy a brand new Giant Revolt to bring our little one on adventures with us. You can imagine our dismay when we found out that our new Giant has a thru axle and Thule had their adapter axle on back order until at least the end of the season. We were just about to give up, return our new bike and sell our kid trailer, when I discovered the Robert Axle Project. Wow, these folks are designing great products. It was more affordable than Thule’s axles and really easy to install. I’m very impressed by R.A.P. and will highly recommend you guys to anyone who asks. It’s no wonder that all the reviews are 5 stars. Great job, thanks so much.

    My only bike without disc brakes was an old road bike with 25mm tires that I was using for a Schw*nn Rascal trailer to get my puppy to the dog park. I bought this thru axle for my “urban adventure” bike and am way happier getting her to the park now.
