Length 174 or 180 mm M12 x 1.75 (BOB111)

Yes, we do have thru axles for BOB Trailers! This is where it all began for The Robert Axle Project. As avid BOB Trailers users since 1999, we are big fans of grabbing our BOB trailer and setting out on a bike tour, a day of trail work, or running errands around town.

Many of today’s modern bikes include a 12mm thru axle that attaches the rear wheel to the bike frame. Thru axles result in a better ride—stronger, safer, more rigid and responsive. When we found out that we couldn’t attach our beloved BOB trailers to our new mountain bikes, we sought a solution. After an extensive search we decided to solve the problem ourselves, and so it began—The Robert Axle Project.

The Robert Axles for BOB Trailers are specifically engineered to attach the proven BOB Trailer to your thru-axle equipped bike. Use our Axle Finder to choose the thru-axle designed for your bike. Then just add the “bobbins” from your stock BOB quick release to your Robert Axle, attach your trailer, and go.

Topeak trailers:
sorry, we don’t have a solution for the Topeak trailer. It is a unique connection system and we just haven’t seen enough of them to warrant a production run of multiple sizes of axles.

Burly CoHo trailers:
We do not make axles for Burley COHO trailers.
