Okay, I've got to call you on this one. Drag losses in all bearings combined (hub, BB, pedals) is much less than 1% of power. Even if Fulcrum 1 Racing wheels had absolutely zero bearing drag, you couldn't increase your speed by 1mph (uphill, downhill or on the flats).redline8 said:My last set of wheels were Velomax Ascent II's. The Fulcrum 1 Racing wheels are slightly heavier, but this is more than offset by the superiority of their hubs. These wheels spin very freely and I have been able to increase my speed on a fairly long and steep descent by more than 1 mile per hour.
Not really. Fulcrum is essentially a way for Campy to get their wheels on more bikes. The idea--or so it is assumed--is that Shimano users are more likely to put Fulcrum wheels on their bikes than they are Campy wheels, even though Campy wheels can be bought for Shimano flavors, too. Fulcrum may make use of the popularity of the Ksyrium look, but so do others.sbindra said:Aren't the Fulcrum wheels basically the same thing as the Mavic SSL? The Fulcrum 1 seems kind of expensive when the Mavic SSL weighs about the same, the hubs are known as being the best quality and the weight of the wheels is about the same.
