All these comments are great. We find products that are unique and will help the athlete. To clear up skeptism. We started out hoping that we would be believed. We had tons of skeptism but nowwe constantly get emails were guys quoting data off their powermeters hr monitor etc where there is improvement,. All are showing better than what we quote. What bikemax says about pushing down is because the hardest part of the stroke is the deadspot at 12 on the clock. here you want to push forwad but you can only push down. So therefore we always have a very big push stroke instead of an even stroke. Q rings oval allow for a very small deadspot and a three tooth larger power stroke, which is between 3 & 6, on the clock resulting in higher accelration through the deadspot reducing the effort needed as the dead spot reduces to 50t on a standard 53 Q ring. So yes they do work, yes they increase power yes they do make it easier on the knees yes they do reduce lactate levels. thanks for the support
