Anyone know anything about the custom Kurt Kinetic trainer, the AC Pro? Sounds promising due to the heavier flywheel (12 lb versus 6.5 on standard Road Machine). But what about the custom resistance curve? They talk about sthe tandard resistance unit having an RU of 87; I used the calculator at analyticcyling and it said I need an RU of 79. What's the difference? Is that a significant difference?
Can anyone advise?
