Shimano Ultegra R8025 2x11 Speed Short Reach Disc Brake Disc Brake Callipers
  • £334.99

Featuring a smaller lever size and new positioning, the Ultegra R8025's lever improves the overall braking and shifting experience for riders with smaller hands. With a redesigned internal shifting unit, you'll benefit from its quick and intuitive gear changes and operation. Enjoy greater control in all conditions with some of the best technologies at your fingertips helping you wherever the road takes you. Behind the "click" you hear and feel every time you shift, is its Shimano Index Shifting System technology providing you with light, precise and consistent gear changes. Completing this set is a powerful flat mount caliper which gives you constant stable braking without any power loss. Its oversized pistons use Ice Tech technology to achieve an optimised low weight, high rigidity and excellent heat dissipation. Furthermore, this technology transfers hydraulic power directly to the brake pad and ceramic material is used to avoid heat transfer. As a result, you'll benefit from longer lasting stopping performance and modulation, making it an ideal upgrade for going further than before ride after ride.

Shimano Ultegra R8170 C36 Carbon CL Disc Wheel - Black - Rear}, Black
  • £649.99

Shimano Ultegra R8170 C36 Carbon CL Disc WheelThe Ultegra R8170 C36 Carbon CL Disc Wheel from Shimano is the ideal aerodynamic and Tubeless Ready road race wheel for steep climbing events, fast sprints and versatile all-day riding performance. Full carbon rim construction with Shimano D2 rim profile and a centre lock disc rotor mount, this top-tier road bike wheel is stiff, flex free, aerodynamically optimised, will ensure exceptional braking efficiency in all weather conditions.With a shallow-depth aero profile and lively acceleration, the Ultegra R8170 C36 wheelset is a climber's delight that delivers performance every road rider will appreciate. With the speed and efficiency of tubeless tyres, the everyday performance of a shallow, aero profile carbon rim, and the convenience of 11 and 12-speed compatibility, the new Ultegra R8170 C36 wheelset is an upgrade for any road bike. Centre-Lock Disc Rotor MountThe Centre Lock system makes an easy rotor installation possible with a spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency. D2 Aerodynamic Rim ProfileAerodynamic performance is affected by wind direction. To create the D2 rim, Shimano engineers considered both frontal and crosswinds, aiming to achieve optimal performance in real-world riding conditions. Extensive prototype testing, in the wind tunnel and on the road, proved that a wide rim shape with a deep tire bed performs best across a wide range of conditions. At yaw angles ranging from 0 to 15 degrees, the Shimano D2 rim profile reduces air drag better than others aero shape rims. This rim design also boosts lateral wheel stiffness and offers improved vertical compliance for increased control, comfort and durability on the road. Shimano E-Thru Axle SystemThe tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15 mm thru-axle system is 15% stiffer torsionally and 25% stiffer in transverse shear than a traditional 9 mm quick release front axle system. High rigidity is secured while keeping the optimum weight balance. The E-Thru axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed. Rear Wheel OPTBAL Spoke SystemThe OPTBAL rear wheel spoke system features 21 spokes—14 on the drive side and 7 on the non-drive side. Cassette spacing in today's wheels produces unbalanced tension in traditional 1:1 spoke systems. This unbalance is intensified with the 11-speed cassette, producing nearly double the tension on the drive side spokes. Generally, high and low tension spokes have respectively tendency toward breaking down and coming loose spoke nipples. Unbalanced tension affects durability and strength. The OPTBAL design rebalances spoke tension, enhancing wheel rigidity and strength for a more durable wheel.
