5. $11,000: Cannondale F-SI Black Inc.
Yet another ultra-expensive race hardtail, Cannondale claims on their website that the F-SI Black Inc. is “the fastet [sic] XC hardtail ever made.” While that claim is highly debatable, this is undoubtedly a carbon wunderbike of the first order.
The F-SI Black comes spec’ed with Cannondale’s proprietary Lefty 2.0 Carbon 100mm XLR suspension strut, a Shimano XTR Di2 2×11 drivetrain, XTR Race brakes, and carbon ENVE M50 wheels.
