A thru-axle adapter for BOB Trailers! These Robert Axles for BOB Trailers are specifically engineered to attach your BOB Trailer to your 12 mm thru-axle equipped bike.

  • This axle is compatible with BOB Trailers.
  • The true length of the axle shaft is 178 mm, but can be shortened using the included spacer to 175 mm or 172 mm. Please note: Thru-axle lengths do not equal hub standards. An axle has to be longer than the hub to fit in the frame. A 12×142 hub does not equal a 142 mm long axle.
  • This axle has a 1.5 mm thread pitch.
  • The axle shaft and axle end are precision CNC machined.
  • The axle shaft is 7075 aluminum and hard black anodized for rugged durability.
  • The axle ends are stainless steel, which allow for mounting of the BOB Trailer bobbins.
  • No special tools required. Design allows for installation or wheel removal using your standard 5mm hex wrench.
  • Please note: This axle does not come with the BOB Trailer bobbins. Those are available separately, here. Or you can reuse your bobbins from the stock BOB Trailer Quick Release that came with your trailer.
  • Designed, built and quality tested in the USA. Proven around the world.

    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.

    Perfect fit with my old BOB gear trailer and my new Ibis Mojo 3! Excellent work, guys!!

  9. Don Olsson (verified owner)

    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.

  10. Owen Rodabaugh (verified owner)

    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.

  11. Tom McGreevy (verified owner)

    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.

  13. Brandon (verified owner)

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

  14. Luke (verified owner)

    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 ❤️

  15. M. L. (verified owner)

    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!

  16. Ace Brown (verified owner)

    Second time I’ve used a Robert Axle and both times find they fit perfect. It’s a beautifully machined and great fitting product.

  17. Jeff Sparman (verified owner)

    Worked perfectly I have a BOB trailer for trail work and wanted to use my 2021 OTSO Waheela C with 700c wheels, to tow various tools to do .trail maintenance. Easy installation, high quality product that is pricy, but but well worth it.

  18. Ianik Guy-Michaud (verified owner)

    Excellent produit, très bonne assistance pour s’assurer de commander le bon produit.

  19. Chris Tauscher (verified owner)

    I own a Salsa Cutthroat 21 and wanted the ability to carry trail working tools and maybe more gear bike packing. They had exactly what I needed to pull a BOB Trailer. Works great!
    They even reminded me to get the bobbins which I was missing.
    Thanks for the help.
