Description

Capable of adapting to many constraints, the SHIMANO GRX RX820 12-Speed Mono 40 Crankset (equivalent to the Ultegra range) is specially designed for Gravel riding. In this version Mono, it incorporates a chainring of 40 teeth.

The Japanese brand made a strong statement with the GRX. With a chainline offset of 2.5 mm to the right, it allows the fitting of wide-section tyres up to 42 mm.

The crankset's teeth also adopt the Dynamic Chain Engagement design for a perfect chain retention on the roughest terrain. Its aluminium construction makes it both robust, precise and formidably efficient. The single-chainring setup finally allows for simpler and more intuitive riding while guaranteeing great versatility thanks to the 12-speed cassette. You will be able to climb mountain passes and tackle the steepest gradients with ease.
