Our current trailers come with a Steel Hitch which is offset towards the rear of the bike to allow for additional clearance and compatibility with most 29 inch tires.
Depending on your different bike axles, an adapter may be necessary to install the Steel Hitch. The Hitch Guide is a step-by-step guide how to identify your bike axle and dropout style to see if any adapters are necessary.
