Sigma Sport Carbon Fork Steerer Bung Top Cap + Alloy Bolt
Manufactured by Token, this custom Sigma Sport top cap and steerer bung is a quality piece of kit and will leave in no doubt where your allegiances lie. The Aluminium top cap is laser etched and has a low, sleek profile, with a tapered black alloy bolt being used rather than steel.
