If i still biked a lot i would definately get one of these, but i dont really. Anyway the thought nehind this contraption is that you are supposed to be able to drink faster in a bike race. (kinda like eliminating pitstops in a rally) But i don’t see why any person who just likes to take his/her bicycle to work cant take good use of this, it is really quite smart. What it is is a canteen/tool pack mounted to the rear of the seat holds 42 ounces of water which is made accessible to the rider via a frame-routed tube system that ends in a tethered valve held securely to the handlebars with magnets. This allows the rider to grab a quick sip while not having to worry about reaching or properly replacing a bottle in a holder. And on a hot day it keeps a heavy pack full of water off their backs. Available sometime in July with an MSRP of $79.99.
