The only upright style bike mount that will work with fenders is the Raptor Aero. Our other upright mounts will not work if your bike has a front fender as the rear support hoop for the front wheel sits where the fender is located which prevents the hoop of the rack from securing the front tire in the proper location.
Do not use the Raptor Aero on a carbon framed bike!
