Make sure that the cone is wedged securely into the stays. The knob should be finger- tight; do not overtighten. The hitch should not move, but should allow the bicycle complete movement, including lying it down on the ground. It should clear any racks, bags, or fittings you have on your bicycle. If there is any interference, contact your Burley dealer.

IMPORTANT: Remove trailer from your bicycle when it’s not in use to prevent deforming the plastic hitch.
