Carbon fiber is a wonderful material that is both lightweight and strong. Just about every part on a bicycle can be made out of carbon fiber. When you're installing a carbon fiber part though, you never want to overtighten it. Unfortunately, when carbon fiber parts are tightened down to their max torque, they can still slip. That's where Muc-Off comes in with their Carbon Gripper. It is a highly efficient carbon fiber assembly compound that creates friction between carbon parts that prevents them from slipping. You can use this for your seatpost, handlebars and stem.
