(3 customer reviews)

$ 62.00

A 12mm thru-axle adapter for BOB Trailers! These Robert Axles for BOB Trailers are specifically engineered to attach the proven BOB Trailer to your thru-axle equipped bike. Take full advantage of your modern bike with 12mm thru-axles and harness the rigidity of the thru-axle to haul your BOB Trailer.

Please note: The dimension listed is that of the axle shaft because thru-axle lengths do not equal hub standards. ie 12×142 hub is not a 142mm long axle.

    This thru-axle worked perfectly with the Bob trailer. I very much appreciate the existence of The Robert Axle Project. Thank you.

    I’m very impressed with this product. It is really nice to have my Ibex attached behind my suspension bike. Also very fast international shipping. The Robert Axle Project, big thanks for being around!
