Rotor CX Narrow/Wide Q-Ring 110BCD

Rotor CX Narrow/Wide Q-Ring 110 BCD

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 that’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 QCX1 model features the ever so popular alternating thick/thin, single-speed tooth profile that ingeniously retains the chain to prevent it from jumping off even when the cross course is at its meanest, and without the use of a clunky chain guide. You’ll also be glad to know that installation does not require disassembling the crank from the bike, making it easier to own multiple rings with different tooth counts for different rides.

Whether you’re a hard-nosed cyclocross racer or an adventurous gravel rider, mounting a Rotor QCX1 ring to your steed is a sure step toward increased endurance, explosive sprints and graceful climbing.

It really works as claimed
This ring does two things well: Its oval shape with multiple settings allows the rider to orient it for maximum power--I have these on three bikes, and Q-rings are a true advantage. The thin-thick profiles of the teeth really do keep the chain on when using a one-chainring setup. Also, Jenson had it in stock and shipped it very quickly!

Is this compatible with a Shimano Ultegra 6800 crank?

BEST ANSWER: I do not believe so. Even though the BCD is the same, the 4-arm configuration of the Shimano crank places the mounting spots into areas on the chairing where chainring bolts will not attach. Even if you could mount it, the orientation of the oval would be wrong.
