    I received my axle a week ago and tried it last weekend. It does what it’s ment to do. Keeping the wheel of my Canyon MTB spinning and pulling my BOB trailer. Great! I specially want to mention the excellent service of the Robert Axle Project people since I had some troubles with the delivery due to customs in Belgium. I had some great assistance and proposals to resolve the problem from Chris. Thank you Chris!

    Ordered the Axle for a BOB trailer for my MTB and no problems getting it delivered in the Netherlands. It arrived in a few days with zero grief from customs.
    Perfect fit. Did a test ride the other day and all went good.

    thanks a bunch

    I received my axle in just a matter of a few days. The instructions that came with it and the videos are great and the installation of the axle is simple. Even for someone like me with limited experience working on mt bikes. In addition the website with all the recommendations for pulling your BOB trailer is super helpful.

    I too want to mention the excellent service I received from the folks at Robert Axle Project and highly recommend this product.

    Thanks for taking this project on: Tom

    I have a 2016 Specialized FSR Stumpjumper comp full suspension 29″ and bought the BOB. Ibex trailer for Hunting and Packing around town. I bought the trailer off craigs list so when I got home and tried to put it on it didn’t work. I went to the bike store for help and one of the employees said ” You need the ROBERT AXLE PROJECT” We went to their website and found exactly what I needed, Bought it and it arrived quickly, I was so excited. It was so simple to install, took 1 minute. I then went and tried to hook up the trailer and AHHH it didn’t fit. Its an older BOB Ibex so the fork was a 26″ and I then had to order from BOB a 29″ fork. I received the new fork, swapped it out and BOOM! PERFECT!! I was Rocking and Rolling!! It was Amazing how simple the trailer pulls behind the bike up/down rock filled trails even over small downed trees on the trail. The trailer was Loaded with 80lbs of gear and the Robert Axle was Flawless, Super Strong and AWESOME!! I want to also give a shoutout to Chris who was Very Helpful as well. THANK YOU ROBERT AXLE!!!! 🙂 🙂

    I received my axle in good order, within two weeks from orderdate despite christmas/new years’!
    The fit is perfect and I took my BOB trailer out for a 3 day winter cycling-camping tour through a nice part of Holland.
    Very satisfied customer and, although the costs are steep, I would advise the products and service by Robert Axle Project to anyone looking for a reliable solution.

    Many thanks for the abilty to enjoy my new gravelracer combined with my old BOB-yak!

    Boston Calling. Specialized Turbo X 2015. It took two business days to get my dream come true axle. It fits better then the original and looks great! Thank you for your beautiful quality product. I’m sure you will do well and I will be happy to pass the word.

    Ordered the axel and had it in a few days. Unscrewed my existing axel and removed it. Screwed in the Robert Project axel, screwed my BOB trailer adapters into each side, and hooked up my trailer. Couldn’t be easier. Have made a few runs with it and all is good. If you need to hook your BOB trailer up to a Mt. Bike, this is the way to go.

    I have a specific trail in mind this summer and it’s rough enough to justify a NEW STUMPJUMPER, wahoo! But my BoB had to come and The
    Robert Axle Project had the solution. Easy peasy. Thanks Bend, you made it all possible.

    I have been pulling BoB with a bike with a quick release. This Robert Axle Project makes my new bike BoB compatible.

    Got a Lynskey MT29 half price on CRC. Didn’t come with axle; some Googling turned up this mob, & the price was not much more than any other axle. So I went straight to this one. The numbers seemed near enough, & one of the included spacers made it perfect. My 29er Bob fork just got here, so my new bike is ready for an extended rumble! Thank you Robert, whoever you are, whatever your name really is, for letting us use our old Bobs with our new bikes. Legend!

    After years of having a “new” bike and without using the “Bobby” trailer, I finally found this perfect product.
    Fits the bike and the trailer after using the “Thru Axle Finder” without any issues.
    First test ride was successful, looking forward now for many other long term trips carrying outdoor gear in the trailer.
