Smooth it out.

No matter how smooth your pedal stroke, your power delivery will be peaky. The transfer of power from your legs to the circular chainring means that some parts of the pedal stroke deliver more power than others. The reason you notice Rotor Outer Aero Q-Rings popping up on so many of the top pros’ bikes is that the oblong shape counters this uneven power transfer to keep things smoother at the cranks. It also means less exertion to achieve the same speed and a reduction of the ‘dead spot’ that you notice in each stroke.

  • 50-, 52-, or 53-tooth

best rings in the market

I've used it several times

great rings to smooth out pedal stroke. Best used in the off season so you can get used to the oval feeling. my hip flexors were sore for a few rides, but once i got used to the rings and got stronger i could tell a major difference in my avg speed and lower hr. i would definitely get another set once these wear out.

incomplete task

Product is perfect, as i expected, however I could install on my bike because when I ask about fitting in my bike I was misinformed.. My bike is 4 bolts, this Qring is 5 bolts.. so I havent use it yet and probably will need to make another purchase or change something else in order to use it.

I like the feeling!

I've used it several times

I don't own a power meter so I can only speak on how it feels. My first impression was that I could move a bigger gear at the same effort, also my cadence was improved on a flat terrain. Haven't try it on a big climb yet.

This thing is magical!

I've put it through the wringer

I don't understand all the engineering behind this-I just know it has improved my biking. Installed on my Cervelo R3 which came with the Rotor 3D crank setup. Cadence is improved over standard round ring. My acceleration in sprints is improved. All my cycling buddies keep asking me what I am doing to get the recent improvements-the only change has been this chain ring. Only downside is after installing (which only takes a few minutes) I worked for days to get the best compromise setup of the front derailleur. Still, I'm a believer...

Spinning eggs for your leggzzz :)

I've put it through the wringer

Rotor chain rings are the cheapest (yes, vs. a pair of carbon rims) and best way to not only increase your speed by about 1 - 1.5 mph with the same effort, but additionally less fatigue over long rides. Yes, they look weird and wobbly when you ride them - but the crazy thing is, it is actually a smoother rotation when riding - doesn't make sense to me still; but really :) Front derailleur set-up is a wee more difficult than the average garage wrench head - but not too bad. I'm using a SRAM Red 22 front derailleur, and the shifts are dead on - ramps are great, no hassles at all. Easy install onto most standard or compact spiders 110 - 130mm. I chose the Aero rings (solid outer ring vs. traditional chainring) it;s about 2 grams heavier than the standard ring, but I'll take that small penalty for the extra rigid performance. Best performance and body upgrade you can get for the $$! I have talked to many a friends in my group - and almost my entire mini-team rides Rotors now and will never go back to a traditional chaining set-up. Also a side note - Both Competitive and Rotor customer service is A+ !


Will this chainring fit on the new Quarq DZero NHB crankset?


I have a Cervelo S3 with the stock Rotor crank. First, will this outer ring work with the stock 3D cranks? And second, do I need the inner Q ring to avoid compatibility issues, or can I stick with the standard circle inner?

Rotor has a crank compatibility list online - I am pretty sure the 3D cranks will work just fine. You don't have to have both rings, but you will need to adjust the FD in any case. If you're going to do just one, it's easier to set up with just the inner ring as a q ring. I found that I needed some of the shims they sell separately to move the derailleur back and tilt it back to get enough clearance vertically as well.
