Description
If Christoph Sauser can win the Cross Country Marathon World Championships on this Rotor QX1 1x11 Single Ring 76BCD, imagine what you could do with it.
This perfect single speed ring has an increased ovality for this version to 12.5%. This translates into better acceleration, reduced muscle fatigue, smoother torque and improved grip for riding off road.
Rotor have always been thorough when it comes to design, and the alternating width tooth profiles seen here are testament to that. These help prevent your chain from coming off no matter what the conditions. Handily this means you can save the weight of chain guides or tensioners, as you will not need them with this ring.
Please note: For use with Specialized or SRAM single cranks you will require an adaptor spider from Rotor. Please contact us for availability.
