Sharing compatibility with Rotor ALDHU cranks and 4 bolt shimano cranks, this is a versatile chainring. When mounted to ROTOR's ALDHU cranks, these Q RINGS can be adjusted in 1-degree increments. When mounted to Shimano cranks, the chainrings are set to intermediate position OCP3, which is the position most frequently used by road riders. For a perfect aesthetic integration with Shimano cranks, there is a set of bolt covers for the different crank models. * Spider not included Colour: Black Anodized Number of Teeth: 34 BCD: 110x4 Technologies: Alu7075, CNC Q Ring Type: Inner Discipline: Road Weight: 30g (36T)
