Fox uses the same lower legs across all its 32mm stanchion 650b forks, and the F100 is no exception. The asymmetrical, ribbed dropouts drop a full 40mm below the end of the leg reinforced by the crisply finished disc brake mount.
The Fox/Shimano QR15 axle is the best through-axle out there, with an adjustable receiver that lets you set the angle the lever closes at. 80 and 100mm travel versions get the scalloped crown to save a few grams, while 26 and 29in options use a significantly different chassis.
In straight structural terms none are very impressive, but their controlled action on the trail sucks up the flex that’s so obvious in workshop warping tests – they’re actually the most confidence-inspiring short-travel forks around.
Kashima coating is standard on all Fox’s top-end Factory forks (Evolution and Performance dampers are available) and helps create excellent traction through sensitive small bump responses.
But it’s the end stroke control that sets the Fox F100 apart in the short-stroke category, with just the right progression in spring rate. Trail Adjust offers three compression settings (when in trail mode) for further fine control.
The result encourages aggressive rather than defensive riding, and keeps Fox the gold standard for short-travel forks.
