RockyMounts DropTop Adjustable Top Mount


This RockyMount DropTop adjustable top mount bracket only will allow you to secure your bicycle to the Bolt It On crossbar. The mount is able to move in any direction on the crossbar. You can secure your mountain bikes, E-bikes, road bikes and more!

The DropTop mount utilizes a TPU overmolded shim to allow for both 12mm and 15mm axles to fit without the need for switching shims out. It is based upon the same clamshell design as the DriveShaft series, which allows for easy loading and adapts to minor differences in axle diameter or contouring.
