Q-Rings increase your power by emulating a Rotor System crankset in the power stroke and by minimizing the intensity of the "dead spot" zones. By extending the time you spend in the power stroke (where 90% of all power is produced) and smoothly accelerating the legs through the critically weak "dead spots". A 53T Q-Ring, around the upper dead-spot is equivalent to a 51T, but as the pedal goes down and more strength is applied, the equivalent chainring tooth size reaches 56T.

QRINGS

GENERAL INFORMATION

Stealth performance weaponary

Meet cycling's ultimate secret weapon. QRingsoffer some of the performanceadvantages of the Rotor System to those with standard cranksets at no weight penalty.The ease of adaptation and performance benefits they offer make them a nobrainerupgrade for the discerning cyclist: Your "sceptical and infinitley wiser" buddies wontbelieve that your awesome sprints and powerful climbs come from your QRings.

QRingsincrease your power by emulating a Rotor System crankset in the power stroke
and by minimizing the intensity of the "dead spot" zones. By extending the time you
spend in the power stroke (where 90% of all power is produced) and smoothly
accelerating the legs through the critically weak "dead spots", simultaneousley
magnifying the feeble pedal imput in these zones, Q's give that extra advantage you
need to get ahead.

" I have a perfect spin: I don't need help"

Not many people realize that one of the most important reasons to have a "perfect spin"
is to compensate for the dead spot's inherent weakness. Having a perfect spin doesn't
solve the dead spot problem: no matter how perfect your spin is, certain muscles in your
legs will always far outpower others and a vertical crank will never have useful leverage
on the chain. Rotor's QRingsare designed with smooth diameter variations, which
magnify the benefits of a smooth spin by reducing variations in:
-powerproduction,
-rotationalinertia a of the cyclist legs, and
-directional inertia of the cyclists body and bike.

We agree that a smooth spin is crucial to efficient cycling. The QRings'
design reflects the fact that we decided to go a step further, to look at the relationship between the
power curve, total inertia and the spin. The vast majority of a cyclists power is produced
in the down stroke of the pedal cycle, irrespective of pedalling technique. By installing QRings,
the cyclists power production is smoothed out, making a fluid spin more natural. The thing that makes Q's even better, is that the biomechanically inspired diameter variation results in more power output and less lactates giving a genuinely free increase in endurance and power. More...
