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 Dura-Ace R9270 Di2 12 Speed Disc BrakeThe Dura-Ace R9270 Di2 12 Speed Disc Brake from Shimano features Servo Wave technology and is compatible with Shimano Di2 electronic drivetrain systems. Plus, it guarantees powerful all-weather stopping power and flex-free lightweight braking performance thanks to its carbon fibre brake lever and titanium hardware.All-new lever ergonomics on the Dura-Ace ST-R9270 dual control levers bring new levels of comfort and control to road cycling. With the fastest wireless shifting available and even more precise brake modulation, Dura-Ace redefines performance. Now featuring Servo Wave Action brake technology, the new Dura-Ace ST-R9270 brake lever delivers modulation and control like never before. Wireless shifting keeps your bike looking clean while offering the fastest, most precise gear changes available. All of this resides in a Dual Control Lever to employs the most advanced materials to offer lightweight and refined ergonomics that provide comfort and control for the most demanding conditions. Servo Wave Precise Braking ControlWhen 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. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control. Shimano DCL Dual Control LeverDCL stands for Dual Control Lever. It has brake and shifting functions in the system and enables easy operation. Ergonomic innovation is as critical to higher standard performance as the added gearing. The shift internals borrows the robustness from Shimano's MTB technology and is so smooth and effortless that one finger shifts front and rear are possible. Indeed, shifting is the ultimate act of Shimano Total Integration and simply has to be experienced to be understood.
