Robert Axle thru axle for BOB trailer

Thru Axles for BOB Trailers

Yes, we do have thru axles for B.B 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 the BOB 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. This system results in a better ride—stronger, safer, more rigid and responsive. When we found we couldn’t attach our beloved BOB trailers to our new mountain bikes, we sought a solution. 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 the Robert Axle - Axle Finder to find the axle that fits your bike!
