Versatile 1x Gravel Power for Mixed-Surface Riding

Description

The Shimano GRX FC-RX820-1 crankset is designed for riders who split time between roads, gravel and rough backcountry tracks. It balances low weight with efficient power transfer to handle long days and changing surfaces. This is a crankset made for versatility, not compromise.

Optimised 1x Drivetrain Efficiency: Designed around a 1x setup, the FC-RX820-1 keeps things simple and reliable. Fewer components mean cleaner lines, less maintenance and consistent performance in dusty or muddy conditions. Ideal for gravel and adventure-focused riding.

Flexible Gearing Options: Pair this crank with either a 10–45T or 10–51T cassette to match your riding style. Choose closer gear steps for fast-paced gravel or wider range for steep climbs and loaded rides. It adapts easily to varied terrain and rider preference.

40T and 42T Chainring Choices: The FC-RX820-1 is available with 40T and 42T chainring options. This allows riders to fine-tune cadence and top-end speed based on terrain and fitness. A smart setup choice for long-distance and mixed-surface rides.

Offered in 170, 172.5 and 175 mm crank lengths, the GRX crankset supports precise bike fit. It delivers smooth, efficient power with a confident feel on unpredictable surfaces.

Features
  • Gravel-Focused 1x Design: Simplified single-chainring setup delivers reliable performance with lower maintenance on rough terrain.
  • Efficient Power Transfer: Stiff crank arms ensure smooth, direct power delivery across long gravel and adventure rides.
  • Flexible Cassette Pairing: Compatible with wide-range cassettes to support fast gravel riding or steep, loaded climbs.
  • 40T and 42T Chainring Options: Allows riders to fine-tune cadence and top-end speed based on terrain and fitness.

  • Lightweight and Durable Build: Designed to balance low weight with durability for long-distance mixed-surface use.

Technology
