Rotor No Q 46/30 1-piece Double Chain Ring For 3D/3D+ Cranks

This is a really rare super-compact chain-ring set that’s machined out of 1 piece aluminum block. It’s 46T/30T because it’s machined as one piece, Rotor was able to incorporate a 30T as oppose to 34T that’s traditionally on a CX crankset. This is very ideal for those looking to run 2X and for wider range of gears. It is direct mount to Rotor 3D or 3D+ crank arm; it might be compatible with additional crank arm models, but I don’t know which other models this is compatible with.
