Shimano GRX Di2 ST-RX815+BR-RX810 11-speed Disc Brake rear
A central concern of Gravel riders is a reliable braking system with sufficient power reserves, the Shimano GRX Di2 11-speed ST-RX815 STI with BR-RX810 Flat-Mount caliper for hydraulic disc brake is characterized by excellent deceleration performance to maintain control on steep, demanding or even surprising descents.

For gravel, road and cyclocross use: Shimano Di2 11-speed STI Dual Control ST-RX815 + BR-RX810 Disc Brake rear

All STI Dual Controler feature an 18mm higher brake lever pivot axis, a curved lever shape and non-slip textures on the contact surfaces for optimum grip even in the roughest terrain. The STI lineup of the GRX family is complemented by the 1x11-way RX800 and RX600 STIs for the left without switching or DSP functionality, including the 1x11 Di2 version (ST-RX815), whose three switches (two on the side and one on the top of the cap) can be used to operate 3rd devices such as compatible lights or computers.

The GRX brake calipers have a design reminiscent of the SHIMANO Flat Mount models from the road bike sector and deliver equally high braking performance. They also have established features such as One-Way Bleeding and the ICE-TECHNOLOGIES heat management system with brake pads and brake discs with fin for maximum fading resistance.

SHIMANO's GRX, the first Gravel-specific component family designed for both fast progress and safe bike handling on loose surfaces, is the result of an intensive and extensive research, testing and development process that incorporates information and feedback from countless riders on trails, forest tracks, gravel tracks and asphalt all over the world.

SEIS SHIMANO ELECTRONIC INTELLIGENT SYSTEM
The SEIS innovative shift technology is still based on the SHIMANO INDEX SYSTEM (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics. This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobble stone roads and combinations of all of these at the same time. Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting. The shift system allows accurate and effortless shifting in difficult circumstances like when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to mechanical Dual Control Levers so you don’t need to re-program your mind for a new system. 

E-Tube
E-Tube platform offers optimum flexibility on your bike. E-TUBE transmits interactive signals and power supply to each parts by “Plug & play” connection. E-TUBE is no rust, no stretch, no freeze and it ensures advanced low maintenance. And SM-PCE1 connects between PC and components to update firmware. Digital device stay the latest version with updating firmware for improve function.

DI2 (DIGITAL INTEGRATED INTELLIGENCE)
The revolutionary DI2 shifting system solves the challenges drivetrains present to the power-delivery equation in cycling. DI2 gives you instant, accurate, lighting-fast shifts the first and every time, at the push of a button. Even in the most extreme conditions, shifting is precise and controlled. You can change gear even under heavy load while climbing or accelerating. With DI2, you are in complete control.
