Carterwrote a review of Rotor Outer Aero Q-Ring on December 20, 2014
Familiarity: 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+ !
