Chris and Katy from Robert Axle Project are avid mountain bikers, trail builders, bike tourers and BOB Trailer enthusiasts who wanted a way to connect various bike trailers with their thru-axle equipped bikes
- The Robert Axle Project supplies a 12mm thru axle adapter for bike trailers
- 12mm thru-axles come in several lengths and thread pitches. It is important to purchase a Robert Axle that has the same thread pitch as your bike
- Adapters work with many Hitch Mounted Trailers - Thule, Burley, Chariot, Croozer, etc.
- Solid axle is precision CNC machined from 7075 aluminum, one of the strongest aluminum alloys available
- Hard black anodized for rugged durability
- Includes stainless steel axle end which allows for mounting of the accessory of your choosing
- No special tools required. Robert Axle is installed or removed using your multi-tool hex key
- Designed, built and tested in the USA
- NOTE: Thru-axle lengths do not equal hub standards. An axle has to be longer than the hub to fit in the frame. For example, a 12×142 hub standard does not equal a 142mm long axle
