Thanks for the insight - it's starting to make sense. This morning it was fully inflated 23mm tires, and come to think of it, a while back, trying it out with soft 25mm tires on the FG was the most difficult. The rollers are 3" drums, don't have a resistance unit, but they are more difficult to start from a dead stop than I would have expected. As for the stationary bike at the gym, I tried to set the resistance high, but when doing strength/intervals on it, I'm not sure it works - it's like there's
zero resistance until it's time to put forth the effort. Maybe it's supposed to be like that, but I like to have SOME resistance while I'm resting, and I feel like I do on the rollers. I guess the stationary bike just does a better job at providing/maintaining resistance at higher speeds.
