Shimano GRX Di2 FD-RX815 2x11-speed Front Derailleur

Matching the Shimano GRX cranksets, the GRX Di2 FD-RX815 2 x 11-speed front derailleur is also designed for a 2.5 mm wider chain line and thus allow tyre widths of up to 42 mm for rough terrain.

For gravel, road and cyclocross use: Shimano Di2 GRX 2x11-speed Front Derailleur RD-RX815 Braze On

The RX800 front derailleurs are designed to handle the 17-tooth chainring difference of the RX800 48/31T crank, while the FD-RX400 front derailleur harmonizes perfectly with the 16-tooth difference of the RX600 crank for 10-speed with 46/30 teeth. All front derailleurs naturally offer the typical SHIMANO shifting performance and precision. The Di2 front derailleur can be easily and intuitively adjusted using the integrated control functions. The mechanical front derailleurs impress with their smooth-running function with a very ergonomic power curve and the integration of tension clamp and adjustment function.

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.
