Pros & Cons

Pros & Cons

  • The ergonomic design of the GRX RX820 shifters reduces strain on your hands and allows for more control on uneven terrain.
  • The ergonomic design of the GRX RX820 shifters match flare design handlebars and reduce the strain on your hands, for more control on uneven terrain.
  • The rear derailleur has an integrated clutch, meaning you have less chance of your chain slipping or coming off on rough terrain.
  • Large gearing range with 10-51 cassette that will get you up to speed on any terrain.
  • The hydraulic disc brakes are specifically tuned for gravel and off-road use, ensuring reliable and efficient braking performance in all conditions.
  • Although the cassettes have a wide range, they are only compatible with Shimano Micro-Spline bodies. As a result, you will probably have to buy a new body or wheelset.
  • Because you have fewer gears than with the 2x groupset, there is a chance that your cadence may need to be altered in certain situations.
