Rotor Shimano GRX chainring, 4-arm, noQ, 110/80 mm bolt circle diameter for gravel riding

That is why it has four arms and a bolt circle diameter of 110 mm in the large version and 80 mm in the small version. It is made of aluminium and has been CNC-milled. The Gravel Spider from Rotor also allows the chainring to be used with a Rotor Direct Mount crank.
