Zefal's Extra Wet Lube, based on patented technology, has exceptional durability no matter what the conditions. It greatly reduces friction through a layer of ceramic nanoparticles that increase chain protection. This ceramic-reinforced, Teflon-based formula provides performance that is 15% better than lubricants made solely with Teflon. This highly effective lubricant is perfectly suited for cyclists on a variety of terrains who are looking for long-distance performance while cycling through variable or even extreme weather conditions.
