Brand Rotor
Crank TypeTriple
Number of gears 10-speed
Suitable for Boost No


The idea behind the Rotor Q-Ring MTB is simple: any pedalstroke has a “dead zone” at the most vertical position of the cranks. At this point, it is simply impossible to transfer your power to the pedal, making this the point during the stroke a rider wants to get through quickly. Rotor Q-Rings have less teeth on the chainring at this point, making it move past the dead zone faster than a usual round ring. Following this, the chainring offers a longer stroke optimising the length of your pedal stroke. This will theoretically help you get across the dead zone faster, resulting in higher efficiency when entering the optimal drive zone. This makes the entire pedal stroke more effective as a whole, leading to lower amounts of lactic acid being produced and staving off fatigue.

The technology underlying Rotor’s Q-Rings is based upon maximising efficiency. Rotor believes her products aren’t necessarily “faster”, but rather optimise your pedal stroke, leaving you with more energy for longer to ultimately lead to a faster time in your event.

Various scientific studies have proven the positive effect of the Rotor Q-Rings, but perhaps an even greater proof of their use is the sheer amount of Pro-wins realised with the Q-Rings.

Goed product, door de aanbieding ook betaalbaar

Net afgewerkt product. Chainsuck probleem direct opgelost. Werkt prima met shimano 10s. Of ovaal chainring veel brengt weet ik niet. Prijs erg gunstig (aanbieding / uitloop artikel?) Was alleen nog maar in 27t te krijgen. Mantel vergat een herinnering te sturen dat het product af te halen was na bestelling.

Weinig verschil

Het ovale tandwiel van Rotor voor de MTB is gering ovaal Het 34t ovale kettingblad van O.Symetric is veel meer ovaal en dat is voor het klimmen in heuvelachtig terrein beter, voor de vlakke stukken en op de weg is Rotor q-ring weer beter
