Rotor meets the demands for smaller, lighter chain rings with the Rotor Direct Mount Q-Ring. It is a simplified one-piece design that saves about 40 grams compared to other standard set ups. The direct mount chain-rings are machined from a single piece of aluminum, making them lighter and more rigid and durable.
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.

I currently have a 34t Rotor Direct Mount Q-Ring and I really like it.
I currently have a 34t Rotor Direct Mount Q-Ring . Installation was easy and works with Race Face Next SL cranks with direct mount system. The Q-Ring profile is 3 OCP and can be adjusted + or - if you need the timing just right. The default OCP works for me. I have used it multiple time on the trail and no chain drop or flex detected. It weighs 67grams on my scale. It is too bad they don’t have a 36t available which suits fire-roads or pavement riding.
34t Rotor Direct Mount Q-Ring Race Face on my S-Works Epic 29er XC . It is easy to install.
Was looking to give my climbing a bit of a boost, and have heard that the Q Ring was a good option for that. So far it has been great, only a subtle change as far as I have noticed thus far, but well made, installed easily, and runs smoothly.
