Velospring is a German company that makes these beautiful new Walnut bicycle grips with an ergonomic shape. They’re available in a standard version called “sen pur”, but the “sen comfort” are the really neat ones.
Those build in a rotationally sprung system that inserts into your handlebar that lets the palm pad flex under your weight when you hit a bump. The design mounts a leaf spring to one end of the insert and the other end to the grip, using the springs torsional resistance to provide the shock absorption.
Wanna see how it all comes together?
Shown here are the various parts on the left, from the black cylinders to the small silver rings in the middle. Next to those is an assembled inner section, followed by a grip sliced in half to show the insides. The assembled inner piece is inserted into your handlebar and tightened to prevent rotation.
The silver bit protruding from the end (on right, bottom) sticks out beyond your handlebar. The bolt then threads through the wood grip and into the silver piece. That silver piece is slotted onto one end of the leaf spring (top) and can rotate just slightly. The result is about 1/4″ of rotation at the trailing end of the grip, just enough to take the edge off. The design is so clever they even won a Eurobike Green award for it!
