I have seen a few post on Q-rings lately and have a semi-rookie question> What are they and do they work? M understanding is they are more oval shaped and help with your pedal stroke. How? Are they really more effective than a standard ring? Do they come in compact gearing?
Thanks in advance.

Hi Crikey
Q-Rings reduce dead-spot negative effects due to its effective variable gear oval concept. The effective gear is lower at the dead-spot zone, so it is easier, faster and more comfortable (smoother) to pass through it. Once the pedal is over the dead-spot and enters the down stroke, the Q-Rings progressively increase the effective tooth size as more muscle strength is available.
A 53T Q-Ring at the dead-spots is equivalent to a 51T, so it is easier to move through the dead-spot. But as the pedal goes down and more strength is available you can see how the gear (effective tooth size) gets bigger, reaching the equivalent chainring tooth size of 56T during the power phase.
We offer them in 110BCD compact 36/50T gearing.
