When a carbon fiber seatpost, stem, or handlebar slips, it can be tempting to simply over-tighten the fixing bolt. Nor should you use common grease when assembling precision carbon components. Instead, use Finish Line's Fiber Grip, an assembly compound for the precision carbon components used on modern cyclocross bikes.
This product adds friction, helping to reduce slippage when carbon parts are clamped.
Simply apply in a thin film to the clamping areas of carbon fiber seatposts, stems, handlebars, and forks.
