Gravel cycling is rooted in its simplicity, inclusivity, and curiosity. Everyone from first-timers to grizzled veterans counts on Shimano GRX, the industry’s first gravel-specific groupset, for smooth shifting, reliable braking, and exceptional gravel comfort.

This wide ratio groupset features a 10-51T cassette, which is ideal for bikepacking and gravel touring riding. Paired wit the 12-speed gearing it is perfect for adventures and delivers incredible value. The components have thoughtful ergonomic designs and gravel-centric gearing for all manners of unpaved adventures. The 610 1x12 groupset uses a mix of mid-level components alongside top tier GRX 820 parts to deliver precise and reliable mechanical shifting with different gearing ranges to cover the full spectrum of riders and rides.

Shimano GRX RX610 Levers and Shifter

Unmatched comfort and control for mixed-terrain riding and racing. The Shimano GRX 610 is based around the Shimano 105 shifter and borrows materials from GRX 820 shifters. It  delivers light and responsive shifting for mixed-terrain riding. The textured hood and anti-slip brake lever surface increase control on bumpy terrain.

Shimano BR-RX400 Brake Calipers

BR-RX400 is a flat-mount brake caliper with pre-bled hoses. Whilst they do not have ceramic pistons, as found on the top tier GRX 820 groupset. Shimano's powerful braking has been proven in gravel racing around the world.  Rotors are not included, please select the size of rotor suited to your bike. 

Shimano FC-RX610-1 Single Chainset

GRX cranks have a chainline that’s 2.5mm wider than that of Shimano’s road cranks. (Chainline is the distance from the centre-line of the bike to the middle of the chainring on a 1× setup, or to a point halfway between the two chainrings on a 2× crankset.) This increases tyre clearance and works better with the wider rear spacing found on some gravel bikes. GRX 820 Chainset features a four arm design, and the material is machined to reduce weight over other tiers of chainset.

Shimano CN-M7100 12-Speed Chain
