GB® Titanium® ProTOP™ Replacement Nose

The GB® Titanium® ProTOP™ Replacement Nose makes replacement easy. Made of hardened Titanium alloy steel, the nose side plates are injected with Carbon Nitride during the hardening process. This guarantees that proTOP™ is the hardest-wearing replaceable sprocket nose in the world. It self-locks over a solid steel web on the bar body and is held firmly together by three high-tensile rivets. The super-tough, high-tech alloy sprocket glides on precision Swiss bearings.
