The Thule TopRide Rook Rack is a premium fork mount roof bike rack for the bike enthusiast with fast and easy mounting for both Thru-axle and standard Quick-release bikes. The bike slides into the carrier on a guided track on the fork adapter and clicks into place. Fasten your bike to the fork adapter on the ground for easy mounting. The fork mount rack is easy and safe to mount thanks to audible and visual confirmation of correct mounting.
