Shimano GRX FC-RX820-2 Hollowtech II Crankset

Shimano GRX FC-RX820-2 crankset - two chainrings for efficiency on any terrain<\/h2>
The Shimano GRX FC-RX820-2 is a lightweight, very efficient 2x12-speed crank for ambitious gravel rides as well as for aggressive gravel races. The set-up with two chainrings is suitable for all those who want to combine the flexibility of conventional road bike gears with off-road capability. The gear ratio has been chosen so that you can always pedal smoothly. You are fast on the flat and make good progress on climbs, no matter what the terrain is like. Even when riding in a group, you will find the right gear with the FC-RX820. The crank features the proven Hollowtech II design for highly efficient power transmission and outstanding stiffness with the lowest possible weight. One reason for this is that the crank arms are hollow and, like the chainrings, made of lightweight aluminium. The model has a specific bolt circle diameter of 80 and 110 mm. It produces a chainline of 47 mm and a Q-factor of 151 mm, which is a difference of about +3 mm compared to road bike cranks.
