Shimano GRX – United in Gravel

Gravel is the great equalizer. No matter who you are, where you come from or where you want to go. Gravel celebrates individuality. It welds together in a shared passion. It lays the foundation for friendships and creates memories for the ages. Whether you ride one kilometer or a hundred. Whether with professional equipment or without. With a 10-speed, 11-speed or 12-speed gear system. Whether on paved roads, forest roads, back roads – or no roads at all. It does not matter why you are out there, all that matters is that you are.

Shimano GRX shift/brake set consisting of the ST-RX820 Dual Control lever for confident handling and the BR-RX820 hydraulic disc brake caliper for consistent braking performance. For a smooth and at the same time easy maintenance provide the proven One Way Bleeding Bleeding system and the Easy Hose Joint System, which greatly facilitates the brake line replacement.

Shimano GRX ST-RX820 brake/shift lever

Plenty of Flare is a typical feature of modern Gravel bike handlebars. The ergonomics of the GRX ST-RX820 shift/brake lever have been optimized and specifically adapted to flared handlebars. While the grip design reduces pressure on the palm, the textured, non-slip surface of the brake lever blade improves handling on uneven terrain. A tiny innovation in the cockpit for maximum gain in comfort and control. With these prerequisites, the ergonomic brake/shift lever is perfectly suited for long-distance use or full- or multi-day tours in mixed terrain.

The STI lever not only offers maximum comfort, but is also characterized by its smooth, precise and highly responsive shifting functionality across the entire gear range. In addition, the proven SERVO WAVE technology ensures particularly good dosage in terms of deceleration. Adjustable in reach and free stroke.

Shimano GRX BR-RX820 disc brake caliper

The GRX BR-RX820 hydraulic caliper stands for superior braking power in difficult terrain. Thanks to improved dosing and a faster-gripping pressure point, Gravel bikers experience a completely new feeling of control. In addition, the Flatmount disc brake caliper is quieter and easier to maintain than ever before, despite its flatter design. While a 10 % increase in brake pad spacing reduces noise, the proven One Way Bleeding system makes servicing easier.
