SHIMANO GRX crank FC-RX810 | 1x 11-speed | 42 teeth

The Gravel bikes are becoming increasingly popular among cyclists. The advantages are apparent. They have a more comfortable geometry than racing bikes, are also excellent off the paved roads and are suitable for a longer journey. However, the conventional racing bike components reach their limits with these wheels. Therefore, Shimano has developed its own switching groups especially for this genus.

The Gravel crank for the 1-speed fans comes in elegant design and with the Shimano typical excellent workmanship on the market. The chain line of 51.1 mm makes room for wide tires in the frame and optimally positions the chainring to the 11-speed cassette. Nevertheless, the Q-factor with 151 mm has remained in the green range. By grading the pinion block from 11-40 or 11-42 teeth, you can make speed in the plane, but also climb steep climbs easily.
