Made to fit our Bomber and Mini Bomber bike racks just swap the Add-On Front Wheel Holder for one of the fork mounts, and now your front wheel doesnt have to ride in the trunk anymore. Elongated entry slots for the skewer allow the wheel to rest on the platform of the rack, providing additional stability when driving. Made for standard road, cross, disc and MTB wheels. Requires the MTB Plugs (available HERE) to hold a 12/100mm or 15/100mm through-axle. Made from .25 powder-coated aluminum.
