Since 2013, we have been an important part of cyclists’ adventures all over the world. Our BOB Trailer thru axles have millions of miles on them in mountain bikes and road bikes, carbon bikes, fat bikes and e-bikes. Our axles are specifically designed to handle the high-torque loads generated by e-bikes.
Our BOB Trailer axles are not just designed in the USA, but are made here as well. They are machined by avid cyclists, to the tightest standards in the industry. We safety test, to failure, every batch of axles we produce to ensure they exceed your expectations.

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 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.

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.

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.”

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.

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!

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!!!
