The gear ratio of the crankset for 2x12-speed drivetrains is adapted to the different requirements of Gravel use and is ideal for dynamic group rides and aggressive races.
Even on rough surfaces, the close gradation with smaller gear steps ensures a consistent cadence and correspondingly good control, which is necessary to maintain the position in the field. Complementing this, the 17-tooth chainring difference (48/31 teeth) covers a wide range of use, providing a comfortable ride when combined with an 11-34 tooth cassette (CS-R8101-12, sold separately) or 11-36 tooth cassette (CS-HG710-12, sold separately) – whether cruising on flat trails, tackling endless gravel roads or massive backcountry climbs.
HOLLOWTECH II
The guiding principle of Shimano's Hollowtech II technology is the perfect balance between stiffness, stability, weight and rotational efficiency. The goal was to produce a crank that minimises the effort required for the drive and enables more efficient power transmission. An exclusive forging process allows the production of extremely light crank arms that nevertheless guarantee maximum stiffness. The fixed connection of the right arm to the axle of the bottom bracket and its external bearing also serve an optimum relationship between stiffness and low weight.
