Part of the first-ever Shimano groupset that's specifically engineered for gravel riding, the fast and efficient Shimano GRX 810 rear derailleur is ready to take on any adventure. It's fully equipped for the harshest conditions thanks to its toggle clutch and switch stabiliser which can be turned on and off to match the terrain. Topped off with some of the finest technologies around, this is an ideal choice of upgrade for exploring further than ever before. Technologies: Shimano Index System: Every Shimano equipped multi-gear bicycle includes Shimano S.I.S - Shimano Indexed Shifting. It's the technology behind that "click" you hear and feel every time you shift through your gears. That "click" captures the light, precise, and consistent shifting bikes equipped with Shimano deliver. It's the sound of perfect gear changes, of levers directing derailleurs in harmony and the feeling that resonates into your hand, letting you know that your commands are being answered Shimano Shadow RD+: Less distraction quiet drive train. The rear derailleur stabiliser reduces chain slap. A simple solution for chain drop, it's lighter and more efficient than roller type chain device

Designed for the highest speed environments and modern tyre widths, the Ultegra C60 wheelset shares its all-carbon rim profile with Dura-Ace but employs a hub that is compatible with both 11 and 12-speed cassettes. For situations where aerodynamics is the priority, the new Ultegra R8170 C60 wheelset features an all-carbon, 21 mm internal, tubeless compatible rim and a super-fast cup and cone bearing hub that is compatible with both 11 and 12-speed cassettes. Centre-Lock Disc Rotor Mount The 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 Profile Aerodynamic 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. Rear Wheel OPTBAL Spoke System The 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.
