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.

Shimano GRX 810 Dropper Release Disc BrakeReady to thrive in the toughest terrain, the GRX 810 Dropper Release Disc Brake brings you fine speed control and outstanding stopping power in all riding conditions. The perfect addition to your multi terrain gravel bike, Shimano has also added mechanical dropper seatpost control. This means you can easily change your saddle height for a climb or descent without changing your hand position, which is key for staying in control as you’re riding at your limits.Whether you're tackling a challenging downhill descent or exploring new terrain types, you'll benefit from its integrated cable pulling system with an 8.3mm max cable stroke delivering instant saddle height control. Enjoy the freedom of being able to easily raise and lower your dropper based on the terrain conditions with minimal effort from this sleek model.Heat Resistant Disc BrakePacked with some of the finest Shimano technologies around such as reach adjustment, you can fine-tune its feel to suit your hand size, type of riding and individual preferences. Taking braking a step further, its Servo Wave technology makes the initial pad travel fast, so little lever movement is needed to bring the pads into contact with the rotor. This increases your stopping power output rapidly and gives you improved control. Easy to set up and maintain, this disc brake's caliper delivers excellent heat dissipation for greater multi-surface braking control. Its Ice Tech technology allows you to benefit from its high rigidity with an optimised, lightweight construction.Features:Shifter Type: Single lever for adjustable seat postFront or Rear: Front brake with left-hand lever (UK spec)Single or Pair: SingleSpeed: N/A (brake only with dropper post control)Use: Gravel, Road Oil Type: Mineral oilMount: Flat mountReach Adjust: TooledHandlebar Clamp Band Inner Diameter: 23.8-24.2mmAnti-slip ribbed surface texture and brake lever coating Easy and clean bleeding systemSimple wheel replacementIce TechnologiesConvenient tool accessManufacturer's Part Number: ST-RX810-LAWeight: 263gTechnologies:Servo Wave Action: When you pull a Servo Wave brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor.
