Shimano GRX FC-RX600-1 Crankset

Shimano's commitment to gravel and adventure riding is strong, offering two levels of 11-speed components, GRX 800 and GRX 600, which are basically aligned with Ultegra and 105 levels respectively. The GRX FC-RX600-1 Crankset is the single ring version for 1x drivetrain set-ups. It comes with a 40T ring and features the Asymmetric 110 BCD used by GRX 800 and the 2-piece crank design via the 24mm OD Hollowtech crank spindle.

Typical of Shimano, the bottom bracket spindle is the plated steel 24mm diameter Hollowtech II model, so it uses the same external threaded and PressFit bottom bracket options. This single ring model has a 49.7mm chainline and a Q-factor of 151mm. Shimano is offering the GRX FC-RX600-1 Crankset with a 40 tooth chainring (other rings available as solo items), in the normative 170, 172.5, 175 mm crank lengths. The ring itself is the forged and machined aluminum design, with hard anodizing on the teeth for greater durability and corrosion protection. The body of the ring is painted in the black GRX 600 scheme to match the crank arms. The ring tooth profile is the single ring specific Dynamic Chain Engagement, which ensures chain retention and protects the chain from damage. It is compatible with HG-EV 11-speed and HG-X11 Shimano chains.
