Fiber Grip is formulated to increase friction and prevent slippage between clamped carbon fiber surfaces, eliminating the need for excessive tightening. Over-tightening can lead to internal fractures and fatigue in carbon fiber parts. To prevent this, apply a thin film of Fiber Grip to the clamping areas of stems, handlebars, seatposts, and seat tubes. This product is tested and approved by leading carbon fiber component manufacturers.
