SHIMANO GRX RX827 Di2 1x12V Groupset

Gravel enthusiasts above all seek freedom, adventure and the ability to forge their own route. With the new SHIMANO GRX RX827 Di2 1x12V, the Japanese brand pushes the boundaries of innovation to offer cyclists a smooth, precise riding experience completely free from the constraints of cabling. The first fully wireless drivetrain for drop handlebars, it embodies SHIMANO's philosophy: innovate to improve the experience, not simply to change it.

Building on proven Di2 technology and the heritage of the XTR M9200 MTB derailleur, the GRX RX827 delivers ultra-fast and reliable gear shifts, even in the most demanding conditions. Designed for gravel, it stands out for its exceptional robustness: compact derailleur with reinforced protection plate, integrated battery and automatic recovery function in the event of an impact. Thanks to SHADOW ES technology, the derailleur minimises exposure to shocks and resets instantly after a collision, guaranteeing flawless operation on all terrain.

Versatile and compatible with all SHIMANO 12-speed components (GRX, DURA-ACE, ULTEGRA, 105 Di2, XTR and DEORE XT Di2), the RX827 adapts to all riding styles. Cyclists can configure their drivetrain to their needs, choosing a 40 or 42-tooth chainring for optimal development. Installation is straightforward: no specific frame or UDH derailleur hanger is required.

Finally, the new range also introduces the BL-RX825-L hydraulic brake lever, a streamlined option dedicated solely to braking. Combined with the GRX ST-RX825 DUAL CONTROL levers, it offers ergonomics designed for gravel: secure grip, non-slip levers and customisable Di2 buttons for total control, at your fingertips, on every trail.
