Following on the footsteps of our DriveShaft HM and Track we saw and opportunity to improve upon a tried and true design. Introducing the DropTop; our next locking fork mount that grows upon years of feedback and use. The DropTop 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. The DropTop also includes mounting holes for both horizontal and vertical mounting orientations, so it replaces both the DriveShaft HM and DriveShaft Track Mounts.
