Shimano - Ultegra R8000 / 6800 Chainring Bolt Set

Ultra high-performance to a broader range of conditions with a reinforced casing, wider tread cap and dedicated Dynamic:Silica4 compounding to minimize rolling resistance while enhancing wet grip. Our Dynamic:Silica4 compound is formulated to minimize rolling resistance while enhancing wet grip. The R:Shield is a breaker belt found underneath the tread cap, providing an extra layer to improve puncture protection while maintaining optimal rolling resistance characteristics. A clincher tire that is only functional with an inner tube to maintain inflation pressure as defined by ISO 4223-1. The historically standard bicycle tire relies on the use of an inner tube to maintain inflation pressure. The inner tube serves two purposes; maintaining inflation pressure along with providing physical pressure on the tire's bead against the rim hook and sidewall to help keep it safely in place.

The T-GRIP keys are specific bicycle tools. These allen and torx sizes are used several times in cycling technology. Tinkering with the bike is a pleasure with these handy tools. The ergonomic T-GRIP handle lies comfortably in the hand. This allows optimal force to tighten each bolt. The core is made of hardened steel and is therefore durable and strong. The allen variants have a rounded head on the long leg. This makes tinkering from a difficult position possible.
