Shimano GRX RX820 Crankset

Pros & Cons

• 42T can be combined with different cassettes, depending on the terrain.
• The 172,5 mm crank length is the most common choice and ideal for people between 1.75 and 1.90 m tall.
• The single chainring setup is the safest choice for offroad cycling, because it comes with a lower chance of equipment failure.

• A 42T is a tad too large for high mountains and long, steep offroad climbs, but you can always switch out the chainring later.
