Q-Rings maiden voyage
I got around to putting these on and trying it out.
I used Q-Rings, not the QXL which are 'more' non round. I put them on the Addict FWIW.
Small ring is a 36T, thus acts like a 34 and 38 and a 36 in transition.
Large ring is 53T, thus acts like a 51 and 56 and a 53 in transition.
To start I timed the 53T for seated efficiency ala TT, and the little for climbing.
I noticed a difference right off, just in feel. But the two things I noticed most are I was in the 53T most of the 30 miles I rode, and my Heart rate was lower markedly. My average speed was also higher by a bit, and I was trying to not push to normal HR, but settled in on the lower HR.
I did tolerate being cross chained more than usual instead of dropping to the little. It seemed easier to stay in the big ring than usual. And my big ring is usually a 50T or a 52T, so this is bigger @ 53T, no less phasing to 56T
I am surprised at the difference frankly. I did get some behind the knee low pains at a point, but that also settled when I quit spinning higher than usual. I need to try another 30 miler tracking the actual cadence rather than perceived.
