A carbon assembly compound or paste like Finish Line Fiber Grip is an essential component of cyclocross bicycle assembly. Manufacturers do not recommend using grease on carbon surfaces, instead, a carbon assembly paste should be used. This creates friction that reduces slippage without overtightening - a must for preventing carbon fatigue.
Without an assembly compound like Fiber Grip, seatposts and handlebars can slip, giving you that "sinking feeling" - a sure way to ruin any cyclocross race.
Fiber Grip is ideal for connections between threadless stems and carbon steerer tubes, carbon seatposts and frames, and more. It's been tested and approved by leading carbon OEMs.
