Please select options


Yes! 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. Set out on any adventure, big or small. Great for off-road tours, trail building, hauling cargo, and more!

Once you switch to our threaded thru-axle you'll notice an additional benefit: your disc brake will no longer rub. This is due to the more consistent and greater clamping force of a threaded thru-axle vs the R.A.T. system. Consider our Lightning Bolt-on Front axle to rid your bike of the flex from the R.A.T.

- This axle is compatible with BOB Trailers and FOCUS bikes with the R.A.T. thru-axle system and 12 x 148 boost hub spacing.
- Includes a flat and a tapered spacer and replacement R.A.T. nut.
- 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 allows for mounting of the BOB Trailer bobbins.
- Please note: This axle does not come with the BOB Trailer bobbins (those are available separately). 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.
