The Definitive DH Race Fork
The Fox Factory 2021 Float 40 Factory suspension fork has an incredible 203mm of travel and packs a massive feature set.
The Tech Talk
Fox's floating axle system offers a distinct performance advantage because it can match the exact width of the fork's wheel mounting surface to the hub flange spacing, creating a perfect alignment and minimizing friction.
This axle type also provides smoother suspension movement throughout the entire range of travel.
Lower leg channels increase air volume, allowing full travel to be achieved, whereas other systems can nerf travel. Fox's system also continually circulates lubrication between the upper and lower reaches of the legs.
A redesigned arch shape juts farther forward, assuring that there is ample headtube clearance at full compression.
The air spring of the Float 40 Factory fork uses Fox EVOL technology to increase negative air spring volume, optimizing small bump sensitivity. EVOL's linear spring curve delivers plushness off the top, extra mid-stroke support, and more tunable bottom-out progression.
Rounding out the package is a GRIP2 damper that uses Fox's patented Variable Valce Control technology for external fine-tuning of suspension performance. GRIP2 achieves with the twist of a knob what typically requires complete disassembly of the fork.
The Wrap Up
All of the features packed into the new Fox 2021 forks are designed to operate seamlessly with your bike, keeping the stoke high and the radness at maximum.
While all of the technical details may be a bit overwhelming, if nothing else, understand that Fox has done the work so you can have the fun.
