Overview
RockyMounts built the Tomahawk as an upright roof rack that holds the bike by its wheels, with a ratchet hook and wheel straps in place of frame contact.
Wheel-only contact spares the frame, and fat bike readiness plus the strap extensions widen what it carries. The listing does not give a load rating, rack weight, lock details or warranty.
Who it's for
Riders with bikes in the listed wheel range and roof bars of almost any shape. Bikes with front fenders are excluded, and buyers who must know the weight limit need to ask the maker.
Pros and cons
- No frame contact
- Fat bike ready
- Fits all crossbar styles
- Easy-Load wheel straps
- Front fenders not supported
- Load rating not listed
- Upright bikes add roof height
Performance notes
Hooking the ratchet over the front wheel and strapping both wheels holds the bike upright without touching the frame. The swingarm sets the bike on the driver or passenger side. Upright mounting raises the overall height of the vehicle.
