The new GRX wheel supports gravel rides that are faster, further, and more fun. Wider tyres need wider rims to maintain lateral tyre stability at low air pressures. Shimano studied the complicated relationship between tyre size, rim width, air pressure, and tyre lateral rigidity to optimize the GRX rim width for 32-50c tyres. In addition, we pursued the best balance of rim weight, strength, and profile in order to deliver an exceptional gravel wheel.RX870 gravel tuned 12/11-speed 700c tubeless wheelset offering all the technology of Shimano wheels balancing the best combination of rim weight and strength to deliver an exceptional gravel wheelset32mm high profile full carbon rim for improved aero dynamics and durability25mm internal rim width to accommodate a wider section tyre from 32-50mmEasy to use Centre Lock rotor mount for use with disc brakes24 stainless steel butted and bladed straight pull spokes with a 2-cross lacing pattern improve lateral and torsional (power transmission) rigidityElbow-less spokes with alloy nipples make for a strong yet compliant wheelThe hub uses angular contact bearings designed to cradle the balls giving both radial and lateral support for superior strength and durability in real world riding conditions.

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.

The hubs on the Shimano Ultegra RS700 C30 wheels feature high-quality contact seals and the legendary, highly adjustable Shimano cup and cone bearings that provide silky smooth rolling prowess and consistent performance. The rear wheel has been laced together using the Shimano OPTBAL 2:1 spoke lacing pattern. This means the drive side has twice as many spokes as the non-drive side and dramatically increases stiffness and rigidity, which is very noticeable when sprinting and powering out the watts.
