US5 packs fit with alloy hooks and have never been easier or quicker to take on and off, with no loose straps left on the bike. The ultra secure subframe fitting allows tailpack combinations of up to 90-litres and is particularly suitable for bolt-on seat pads and traditional one-piece seats (4 x web loops attach to the subframe and exit at the seat edge) Attach the 4 x alloy hooks to the loops and compress the pack down with the Q/R adjusters. Secure the loose strap ends with the web tidy components and you're ready to go. NB - US-packs can be mounted inline or across the seat.
The US5 can also attach to Kriega backpacks and TANK with either the old style fitting straps or with the new alloy hooks. The US5 also includes 2 x bolt-on Hypalon loops to fit a dirtbike fender. For road bikes the standard 4 x subframe loops are used under the seat. See individual product pages for full fitting instructions.
2 x US-5s can be bolted to the rear fender/side panels to provide 10-litres of storage without compromising the overall seat-height. Extremely effective solution for carrying heavy tools on the trail (even better when used with a Kriega tool-roll, see link below). Packs can be put on either way(zip or mesh pocket) and are easily removed via the 2 x hook straps. NB always use the strap tidy components to prevent web creep.
