Rock Shox: Who obsesses over the weight of their wheel axles? It s ridiculous, right? It s just a rod of metal bolting the wheels to your bike. But then again, Maxle Lite is a nifty thru axle system that makes your bike both lighter & stiffer. & less weight makes it easier to get your bike to do what you want. Especially when you don t need to bring tools to remove it, front or rear. & that extra stiffness gives you the precision to hit your lines no matter how burly. So maybe that obsession isn t so ridiculous after all. Now available in 20 x 110mm & 15 x 100mm sizes.
