ITT: Instant Torque Transfer. That is the best way to explain how riding Lightweight Standard wheels feel. I have around 4000 miles on a set that I took to France last summer to ride in the Alps. I first noticed the ITT, a.k.a. acceleration, on climbs when I got out of the saddle. Then I noticed that when riding with the same group that I normally ride with, other riders were shifting to an easier gear at the base of a climb sooner than I was with the Lightweights. Once I got to know the wheels better, I realized how easy it was to change speed on a climb without changing gears. Speed adjustments were simple and easy by just pushing a little harder on the pedals. I know that sounds simplistic, but it typically takes a lot of effort, mental and physical, to accelerate a wheel when you are setting pace on a climb at your anaerobic threshold. Not so with the Lightweights.
