    Purchased thru axle for BOB Ibex trailer. Perfect fit using template and easy installation video. Have yet to take it out on a ride with the trailer but am sure it will allow me to use my new 29er to pull it instead of having to stay with my old 26. Great job, highly recommend.

    Purchased the thru axle for the BOB Ibex trailer and the product is a perfect match for my bike. The fitting template and installation video is very helpful as well. Because I was purchasing a second hand trailer which did not include the BOB Trailer quick release, I was lacking the stock trailer pins and RAP Bobbins. Fortunately, The Robert Axle Project sells these as well. Great customer service; quick and knowledgeable response.

    Had a work party a few weeks back and used this axle to tow a trailer with two brushers and accessories up and down the Coldwater Lake 230A trail behind my Ibis Mojo HD4. The directions and setup were clear and everything worked as expected.

    Worked perfectly for attaching a rack to my bike which has no mounting points.
    I am very pleased!

  12. Will Ratliffe

    Purchased to enable rack installation on a mountain bike without mounting points. The first axle had a stripped thread; exchange for a replacement was very quick and easy, at which time we realized that either I messed up or the axle sizer did, and we needed a 168 not a 172-178. Again, absolutely no problem to exchange. With the proper one installed the rack fits perfectly. Customer service was as good as it gets.

    It fit well and was exactly what I needed to connect the trailer to my bike. Its machined well and is a great product.

    The axel was perfect, I am now waiting to get my cutthroat back from the shop with a new fork. I am also waiting for a 28 fork for my bob trailer. I am hoping this size axel also fits on my salsa deadwood which also has a 148 boost spacing. Looking forward getting things put together ❤️

    I bought this Bob trailer axle so that I could tow my Bob trailer with my new Poseidon Redwood adventure bike. The axle matching process was easy (even for a new bike not yet listed in the automated matching tool. Installation was simple, and the entire setup has worked flawlessly. I love it!
