The Revelate Spinelock™ seat bag is the most stable, low-profile mounted, feature-loaded, waterproof seat bag available.

It integrates user tested and approved features like a one-way air purge valve, rear light slots, loop and bungee deck, and an external plastic bottom with a new patented attachment system. Stability was the driving element in the design process. If you want something you can pack and forget, the Spinelock is your seat bag.

Its stability system consists of three components: the saddle clamp, seat bag mounted "Spine" baseplate, and pin. A low profile, high strength, forged aluminum clamp works in combination with precision IGUS bushings to form the pin interface. Twin forged upper arms, fastened by Torx-25 bolts, rotate into position above the saddle rails for easy mounting.
