Explanation
Shimano's GRX Group FC-RX810-1 cranks are the hottest cranksets available today for a variety of road conditions and riding styles.
In recent years, the wide narrow chainrings that have swept the market have benefited greatly, and the simple gear system has made it possible for anyone to intuitively change shifts. It also makes it easier to focus your consciousness on pedaling, which should help you maintain your pedaling rhythm in any road condition and increase your concentration on the road.
The GRX Group is based on the newly born riding concept, and there is a need for a system configuration that goes far beyond the concept of motorcycles in the past, so we have secured compatibility with wide tires more firmly than conventional cranksets. I am. The single chainring uses Shimano's Dynamic Chain Engagement Technology so you don't have to worry about the chain falling out.
Of course, the FC-RX810-1 crankset also uses Shimano's proud Hollowtech II system, which has matured through many years of trial and error.
