Shimano - Ultegra R8000 Chainring 52T

The new ContiTube bicycle tube program makes it easier for you to find the ideal tube for your cycling demands. The user-friendly tube system is suitable for any size, length, design, type of valve and perfect for any tyre dimension and riding occasion. Varying tube types can affect your tyres’ handling characteristics: the Standard tube, available in all dimensions is the best choice for everyday cycling whilst Light & Supersonic varieties give racers the option of lower rotating weight, therefore increasing speed. The lightweight tubes have a lower thickness and so it is imperative that inflation pressures are maintained to prevent the risk of pinch flats.

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. Goodyear Bicycle Tires proprietary design that features all the benefits of a Tubeless Ready (TLR) tire but will also better maintain inflation pressure than a traditional TLR tire. A multi-compound material layer is added to our high-pressure Road-UHP tire casing allowing for improved air retention while providing additional puncture and cut protection with minimal increases in weight. Our unique design means more sealant remains after installation, ready for the moment you need it. To ensure the quality and safety of our tyres that we strive for at Goodyear, the fitment of the "Vector 4Season" tyres is close-fitting.
