These are our oval chainrings made for the INspider
power meter or any of our new cranks when used in conjunction with our 4-bolt spider. They are also fully compatible with 4-bolt Shimano® cranks.
When mounted to ROTOR's 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 seamless integration with Shimano® cranks, there is a set of bolt covers for the different crank models.
ROTOR 4-bolt spider sold separately.
