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 bought this bag so that I could carry a 70 ounce hydration pack on my Challenge Fujin SLII, and it works perfectly. It securely holds my hydration pack low on the left side of the bike and out of the way of everything else. I could not be more pleased with this bag. Excellent product!
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.
