GRX is a brand new series of gear components for gravel and cross. Shimano has asked a lot of riders in gravel and cross driving about what they want in a new gear group so that it suits those who ride in that terrain as best as possible.
The chainring are 42T which is a really good choice for mixed terrain, both when the hills are steep and when it has to go fast on the long flat roads.
Singlespeed crankset in the GRX series uses the same tooth profile as Shimano has used on MTB for several years. It is called "Shimano Dynamic Chain Engagement Tooth Profile" and covers a special design of the teeth on the chainring which holds the chain better in place.
The pedal arm is 172.5mm long.
