  • This axle is compatible with BOB Trailers.
  • The true length of the axle shaft is 167 mm, but can be shortened using the included spacers to 152 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 1.0 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.

    Excellent product. I’m using on my Specialized Diverge and it works great.

  2. Darren Hooson (verified owner)

    This axle is well made and fills a need.
    Made my Bob trailer useable on my new bike.
    Excellent service, in stock, and about a week to deliver to Victoria B.C.
    I bought the bobbins as well to keep the original Bob axle for my older bike.
    Thank you Robert Axle Project.

  3. Stéphane (verified owner)

    Excellent product, well manufactured, easy to install.
    Very fast delivery.
    It made my bob Ibex usable with my new Specialized Sequoia, and saved my road bike travel through the alps

    In an age of ever-changing industry standards it is increasingly difficult to retrofit product. Marrying my B.O.B. trailer (bought in 2007) to a 2017 Tallboy simply wouldn’t be possible without this axle. The tolerance, finish and ease of use are indicative of well designed product… further, it’s noticeable that the designers use the product themselves!

    I ordered a 12mm BOB axle for my 2015 Gen 3 carbon Santa Cruz Nomad outfitted with the Kranked Bikes Electric 2,200 watt motor. It installed easily with some parts left over (I assume they were for other bike fitments). I also bought and installed the RAP bobbins.

    Note: I had to spread the BOB trailer attachment arms out about a 1/2″ to get them onto bobbins.

    A week of running logging roads with a 50 lb load on trailer was a non issue. Everything worked and nothing came loose.

    I will be looking to get the 12mm trainer axle for my Santa Cruz Tallboy next

    “I thank you, and my 2013 Santa Cruz Nomad thanks you too. So glad you guys are serious about finding a fix to this BoB thru axle delema. Your customer service was fantastic. You helped me order the correct axle. The axle arrived a day early, which was awesome.Taking it out of the packaging it is a beautifully engineered piece of work. When it came with extra parts and installation instructions I was a little nervous as I’m not that mechanically inclined. (Also, this is my first ‘thru’ axle bike, so you know…) However, it installed easily and fit perfectly, no extra parts needed. I’ve had it out on several loaded rides. My BoB Ibex loaded with all of my camping gear and 6 gallons of water too!
    Dreaming of a 4 day self supported tour on the White Rim trail for my 60th Birthday.”

    Thank you for keep me going on my adventures after getting myself a Specialized Diverge.

    The Holy trinity for traveling is .My bike; My BOB and Me!
    The axle fits like a glove and am stoked to take it around Europe and further…….

    Delivery to Amsterdam, The Netherlands was a non issue as i could trrack it all the way from US to my home in less than 10 days!!!!!

    Thank you so much!!

    Axle arrived in a timely manner, just as advertised. No surprises, no hassle. Thanks for a great product to help with my first bikecamping adventure. Bill M.

  9. Fernando Cubillos (verified owner)

    works neatly for my thru axle gravel bike (Diverge), which I can attach the BOB trailer. My dog loves it!
    Great communication with seller, fully recommended

  10. Javier (verified owner)

    Fit perfect to my Santa Cruz mountain bike. Shipping service no problem! Dreams come true! Thanks!

  11. Rob Olykan (verified owner)

    I was searching for a solution to attache my Bob to my new purchased 2019 Cannondale e-bike, that has a thru axle while i was used to attache it with a conventional quick release. Robert Axle clearly saw the gap in this market. I ordered one and to my surprise it was delivered within 3 days! The axle is really a quality product. Unfortunately the guide lines on the order form were not 100% correct so I had to return my axle to US for one 5 mm longer. Despite this inconvenience I strongly recommend this axle to anyone who is still in doubt. I can’t wait to install my Bob again.

  12. Ton (verified owner)

    Support provided by the Robert Axle project is perfect. Quickly answering questions and delivery is very fast. Recommended!

  13. Sasha Land (verified owner)

    The axle was really nicely machined and high quality. I was stoked to find an option to pull my BOB with a Specialized Crux. Worked perfectly!

  14. Jason Schroeder (verified owner)

    dead-on perfect fit for my slightly unusual thru-axle spacing… they even knew what “SCS” is (see ~2016 to 2010 Specialized bikes)…

    Its even pretty good on weight; not the ultralight 20 gram skewers I had grown to love, but for a 12 mm thru, the weight is pretty impressive.

    I have added the Old Man Mountain rack and it appears rock-solid (and was pretty intuitive to install, too). I am ready for bikepacking… go RAGSLOD!!!

  15. Francis (verified owner)

    Great service and great fit for my bespoke tandem – the sizing chart and help were really useful

  16. Francis Madden (verified owner)

    Great fit and service – size charts and guides really helped to get the right product for my bespoke tandem

  17. Cody (verified owner)

    Bought this to add braze-on screw holes for my Canyon Grail bike because it does not have holes for rear racks. The packaging that this thru axle came in was great and shipping was relatively fast.

  18. Stan rathbone (verified owner)

    I recently purchased the BOB 117 axle to tow my BOB trailer. I found these folks great to work with in helping me decide exactly what I needed. The axle arrived quickly and looks like a quality product. I was unable to make a planned trip and consequently haven’t been able to use the axle but i have no doubt it will perform wonderfully.
