Shimano GRX RX810 11 Speed Crankset 48/31 | FC-RX810-2 |

GRX cranksets are designed for different terrains and styles; They all come with a +2.5mm chain line for wider tires and greater distance to the frame. Single chainring cranks offer the simplicity of single shifting on the rear cassette (options include RX800/600 40T and RX800 42T cassettes) and feature Shimano Dynamic Chain Engagement profile teeth on the front chainring that provide greater chain retention on rough terrain. . Likewise, the GRX double chainring crank RX810 has a jump of 17 teeth, in 48-31T, which is the widest ratio developed by the brand to date. Along with the additional RX600-11/10 46-30T options, the double chainring cranks provide gear ratios wide enough to attack the steepest slopes.

Technologies:

• HG-EV:
  • The HG-EV sprocket cassette is ideal for combining speeds tailored to the cyclist and managing cadence. We provide an optimal 11-speed transmission ratio; You can choose a wider or narrower combination for different cycling styles. The HG-EV sprocket cassette features 11 speeds without compromising durability and HYPERGLIDE's improved 10-speed shifting.
• Hollowtech II:
  • The concept of HOLLOWTECH II technology has focused on producing an excellent crankset to maximize the rider's power transfer. The rigidity of the crankset ensures pedaling efficiency, while its light weight, a key element of the crankset, allows the cyclist to improve his performance over longer distances, where he will have to pedal more. Naturally, SHIMANO has worked to achieve an optimal balance between competing needs for stiffness, while also achieving light weight. HOLLOWTECH technology is an ultra-lightweight hollow crank arm created by SHIMANO, with the company's own forging technology that also allows rigidity to be maintained. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crank arm to achieve greater rigidity and save weight and, thus, obtain a high dimensional balance. The outer bottom bracket bearing system provides better weight distribution and greater pedaling stability for more efficient power transfer. further
