The FastBack 70LS Hydration Pack lives comfortably just left of center on the back of your seat. It's the solution for lowracers and other hard-shell bikes & trikes with limited tire clearance, as well as Bacchetta EuroMesh seats. Stow away a 3L CamelBak Bladder or some gear. Get the Double Century instead and wield another pack of power! Have a 70LS already? Get the 70LS to Double Century Upgrade Kit and boost your capacity!
I was very surprised that the pack didn’t come with a hydration bladder and drinking tube. The tube has to be longer due to the location of the pack. I was also disappointed that there were no instructions or guidance on how to mount the pack. I have finally figured it out, bought a bladder and an extra long tube so after 3 weeks, I may finally be able to use it and see how well it works. I am pretty disappointed in this product and its high price.
