With the proliferation of gravel and adventure road cycling, it was only natural that the company known for durability, long wear and stable precision would release the first component series dedicated to the physical requirements of rough terrain, but built with road concepts. Shimano's GRX 800 series 11-speed group offers both single and double chainring cranksets to couple with various rear derailleur options depending the gearing you require. The Shimano GRX GRX FC-RX810-2 Crankset features the asymmetric 4-arm spider design found on Shimano's road groups, with stouter, more mountain bike inspired Hollowtech crankarms. The 2x spider was built stronger as well, making the 4-bolt chainring options simpler and more cost effective.

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 double ring model has a 46.9mm chainline and a Q-factor of 151mm. The GRX FC-RX810-2 Crankset balances weight and efficiency for mixed-terrain riding. Gearing options cater for the specific demands of gravel riding and to maintain tighter gear steps for maintaining pedaling rhythm. The 2x11-speed crank is available in a 48-31T chainring combination and 170, 172.5, and 175mm crank arm lengths. The rings are forged and machined aluminum, with hard anodizing on the teeth for greater durability and corrosion protection. The body of the outer ring is painted in the gray GRX scheme to match the crank arms. It is compatible with HG-EV 11-speed and HG-X11 Shimano chains.
