It's a crafted piece of bicycle jewelry, midway between intricate and simple. But this bauble perched off your rear wheel actually does something very useful: It turns the longest roads into your playthings. With this nifty little gadget you can ride as far as you can see on a clear day, make it up any road that they are crazy enough to pave (as well as trails), and be back in time for dinner. It answers to your will by mere attenuation of cable tension. The symmetry of the jockey wheels, the unity of the parallelogram shape and its movement under tension are all about function, and so, by at least one definition, it has an inherent beauty. It is this beauty, plain-spoken function and potential that you honor: Presenting the R•MECH shirt … Next: Thermal Bike Bottle-> The R•Mech T-Shirt The fabled Rear Mechanism proudly and simply stated on the front.
