Detail description for Rotor Q-Ring Pair 110BCD 34/50
Rotor Q-rings give you a smoother pedal action and help reduce build up of lactates at threshold.They give you assistance deadspot by reducing the effective gear, and also help you utilise the Q-moment(point of most force) by raising the effective gear.
34/50 Road Chainrings for use with 110BCD Compact Cranks - Please note these chainrings are not compatible with Shimano Compact Chainsets - you will need Rotor OCP3 34/50 Chainrings for these. If you have any doubts call the shop on 01908 260322 for advice.
Meet cycling's ultimate secret weapon. QRings offer some of the performance advantages 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 nobrainer upgrade for the discerning cyclist: Your "sceptical and infinitley wiser" buddies won't believe that your awesome sprints and powerful climbs come from your QRings.
QRings 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', simultaneousley magnifying the feeble pedal imput in these zones, Q's give that extra advantage you need to get ahead.
Rotor's QRings are designed with smooth diameter variations, which magnify the benefits of a smooth spin by reducing variations in: power production, rotational inertia a of the cyclist legs, and directional inertia of the cyclists body and bike. For the vast majority of cyclists power is produced in the down stroke of the pedal cycle, irrespective of pedalling technique. By installing QRings, the cyclist's 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. Orientation and adjustability is key.
The shape and ovalization of QRings isn't everything: what really sets them apart, is the basic orientation and the possibility to adjust it. The problem with normal ovalized chainrings is that they only work in one set position on a bike. As soon as the cyclist's hip moves, the angle of the crank at the minimum and maximum power points changes, which in turn changes the orientation of the chainring in regards to the cassette. The key was to make Q's compensate for the effects of varying riding positions, leg inertia and bike inertia. The basic orientation of QRings, based on power and inertia studies, is one of the reasons QRings feel so natural. The revolutionary narrow variance OCP (Optimum Chainring Position) system gives the cyclist the possibility to choose from an array of settings within the small, crucial range of useful orientations. Why? Because everyone has a different riding style, a different bike setup and a different pedalling style. The OCP system guarantees you personal optimization of the chainrings to make them work best for you, with your riding style, your bike and the terrain you're dealing with.
Price is for chainrings only and does not include crank.
