Fat Paw Lock-On Grips bring the same texture and feel of the popular Fat Paw silicone foam grips to the lock-on grip format. This means that they are comfortable, easy to install, and have excellent vibration-damping qualities. The installed diameter of Fat Paw Lock-On Grips is the same as the Fat Paw silicone foam bike grips, at 36mm. They are compatible with all standard mountain bike handlebars.
