Description
The Universal Adapter for Bike Trailer screws onto axles with an M10x1.0 thread.
Common hubs with this axle are Rohloff, Enviolo, Shimano Nexave, SRAM I-Motion, and SRAM Torpedo. Robert Axle Project’s M10x1.0 adapter for bike trailers is designed to allow the attachment of any bike trailer with a hitch. This adapter is suitable for any bike trailer that has two wheels and a single attachment point to the axle.
It is the axle and the contact surface on the bike where the hitch is to be mounted that determines whether you need an adapter for your bike.
If you are unsure which adapter you need, you can check out our Adapter Guide.
Some common challenges this bike trailer adapter solves:
- Loose Hitch: The hitch on the bike trailer tends to loosen easily, requiring constant retightening.
- Improved Stability: We find that the axle and hitch to the bike trailer stay significantly better positioned with this adapter.
- Note: It is recommended to check and retighten periodically. Always ensure the hitch is secure before connecting the bike trailer, and always use the trailer’s secondary security feature.
- Frame Space: The “hood” or slot in the frame where the axle sits (also called “dropout”) may prevent the bike hitch from fitting flush against the bike frame.
- Adapter Shape: The shape of the adapter fits into all the dropouts we have tested, and once mounted, it provides a good base for attaching all types of bike hitches to the trailer.
- Diameter: 20mm (about 0.79 inches)
- Proximity Issues: Bike trailer hitch and coupling may come too close and interfere with brakes, wheels, or the frame of the bike.
- Extension: The adapter extends the hitch 28mm (about 1.1 inches) further from the bike.
- Nut Replacement: The adapter replaces the “nut” on the axle, allowing it to be mounted directly on the existing axle. The bike trailer hitch is then mounted on this. Watch the video below for installation instructions.
