Here are the new Ethic grips, the Slim. They do not come to replace the original ones, it is an alternative: Finer. 30.5mm against 32mm, and in length 160mm instead of 170mm. (21g lighter)
Also, the bar-ends are integrated! An Ethic innovation and a world first. The Ethic grips are the best-selling grips, comfortable and durable, all that was missing was a thinner version to satisfy everyone.
