Shimano GRX RX820 12 Spd Double Groupset - 11-36t
The Shimano RX820 is a gravel-specific 2x12-speed groupset with a 31-48 tooth gradation at the front and an 11-34 or 11-36 tooth cassette at the rear. 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. In keeping with the slogan " Undroppable" , you never get dropped and master every challenge. In any case, you will benefit from the reliability, durability and performance of the GRX RX820. With this groupset, Shimano has once again expanded the range of its gravel components to reflect the spirit, individuality, sense of freedom and community of gravel enthusiasts. The groupset also includes two shift/brake levers, a front derailleur, a rear derailleur, a Quick-Link chain and flat-mount disc brakes.
