The RockyMounts DropTop is a compact locking fork mount designed for vans, utes, truck beds and custom bike-carrying setups.

It works with modern road, gravel and mountain bikes using 12mm, 15mm or 20mm thru-axles up to 110mm wide. The same TPU overmoulded shim works with 12mm and 15mm axles, while 20mm setups simply require the shim to be removed.

The wide opening makes loading easy, while the locking T-bolt and TPU contact surface help secure the thru-axle once the bike is clamped in place. It can be mounted vertically or horizontally, making it a tidy option for van builds, ute trays, truck beds and custom track systems.

For bikes using a 9mm quick-release skewer, RockyMounts also offers a QR Dummy Axle separately.

Simple, secure and built for custom installs where you want your bike locked in without taking up unnecessary space.
