Pro tip
This adapter is not a thru-axle — it replaces the non-drive-side nut on a solid rear axle. If your bike came with a solid axle and a nut, unscrew that nut, thread on the adapter, tighten it, and your trailer hitch mounts onto the adapter's stud. If your bike has a thru-axle instead, you need a RAP thru-axle, not an adapter.

How do I know if this axle fits my bike?
Check your bike manufacturer's spec sheet for rear-axle diameter, thread pitch and total length. Or unscrew your existing rear axle and read the markings. Or email fit@hitchabike.co.uk with your bike make, model and year.

A 5 mm Allen key — the same one you likely already carry.
