Rotor Q-Ring Road Chainring 110BCD 5Bolt

Rotor Q-Ring 110 BCD Chainring

Whether it be a pro rider on TV or a fellow local cyclist, you may have seen these ovalized chainrings at one time or another. You then probably immediately asked yourself, “What do they do?” Let us explain.

Rotor Q-Rings vary drivetrain resistance during a pedal rotation to align with your leg’s natural strength spots and weak spots to boost your overall efficiency. In doing so, Q rings wisely utilize the strongest muscle groups to increase positive work, while picking up the slack in the weaker zones to reduce the negative work, potentially increasing a competitive cyclist’s performance by as much as 4 seconds per km in an all-out sprint. That may sound miniscule, however it’s twice the benefit of an aero wheelset, and in a sport where a second can be the difference between the top step of the podium and no podium at all; these proportions are substantial.

Through Rotor’s Optimum Chainring Position (OCP) you have approximately 5 degrees of adjustment meaning you can micro adjust the position of your Q Rings to suit your style by simply making corrections toward both comfort and efficiency. Machined from 100% CNC T6 7075 Aluminum, the Q-Rings are compatible with all 10 and 11 speed groups.

Whether you’re a powerful cyclocross racer, a strong road racer, or a focused triathlete, mounting Rotor Q-Rings to your steed is a sure step toward increased endurance, explosive sprints and graceful climbing.

Features:

  • Tooth Options: 34t, 36t, 38t, 44t, 46t / Aero - 50t, 52t, 53t
  • 100% CNC, T6, 7075 Aluminum
  • Steel shifting pins
  • 110 BCD
  • 5 OCP regulation points
  • Design works for all 10 and 11 speed groups
  • Some cranks require specific Q-Rings

Hello - looking for a SET of Rotor rings for my Campagnolo Record crank -5 arm - not the newest 4 arm design - the one just before it - it currently has 52/36 rings with 110BCD. Do you have in stock? thx.

BEST ANSWER: These Rotor rings will not fit your 5-arm crank. Not enough clearance from the crankarm.
I have need on my old school mtn back for 52T ring. It's a shimano 110mm, 5 bolt pattern. Will this or a different ring work?

BEST ANSWER: Should mount up fine, although this chainring is optimized for use with Rotor's road chainrings, and not MTB chainrings.
