Technically Scott's is better because of the two speed feature. Scott's has a built in feature that when you dial in more resistance in the low speed, the high speed resistance will automatically decrease resistance, it works the other way as well when you decrease the low speed resistance. There's no need to really increase the high speed much more than the factory setting at "#2". The most I've ever did was 3 but that was at a very bumpy track.yeah thats why i was leaning towards the gpr cuz of easier adjustment while riding, but is the scotts better since it has high and low speed adjustment separately?
