Optimal gearing for spirited group rides and aggressive racing

The SHIMANO FC-RX820-2 balances weight savings and optimal efficiency for mixed-terrain riding and racing. Double chainring gearing caters to the segmented demands of gravel cycling, maintaining the tighter gear steps needed to maintain your position in the bunch. The 2x12-speed crank utilizes a 48-31T chainring and comes in 170, 172.5, and 175 mm crank arm lengths.

Features:
- Smaller gear steps for cadence control on mixed-terrain riding. Gravel-optimized gear ratios preserve riding rhythm on rough surfaces
- Wider gear range. 17T range covers array of riding conditions
- HollowTech II allows the bottom bracket bearings to be spaced wider apart, enabling the use of larger bearings and an increased axle diameter
