Welcome to the coronation. Fox 36: The undisputed all-mountain champion gets a new crown. For MY23 the Fox 36 receives an update in the form of a new crown with updated design and engineering for more steer tube overlap improving durability and maintaining stiffness while dropping 20 grams.New Crown - Lighter by 20 grams, while increasing steerer-tube overlap at the CSU, the new crown design improves durability while our engineering maintains stiffness and drops weight.Axle - Kabolt, a lightweight bolt-on floating axle to shave grams and increase torsional stiffness via a sleeveless, single-sided pinch bolt design.Lower Leg Bypass Channels - Increasing air volume within the lower legs reduces the amount of additional unintended pressure ramping. Lower leg bath oil also circulates to the upper reaches of the legs, continuously lubricating the foam rings and bushings as the fork compresses and extends through its travel.Lower Leg Bleeders - Allows for atmospheric pressure equalization for better fork performance, allowing full travel to be achieved and increasing small bump sensitivity and responsiveness.Lower Leg Arch - Our new lower leg design pulls out all the stops, shaving every possible gram while making sure not to compromise stiffness or strength requirements of modern enduro and gravity-style riding.GRIP2 - Unparalleled ride quality and ultra-precise adjustability. Allows for external fine-tuning of suspension performance thanks to our patented Variable Valve Control (VVC) technology.Float EVOL - Optimizes small bump sensitivity by increasing negative air spring volume. Its linear spring curve delivers plushness off the top, extra mid-stroke support, and more tuneable bottom-out progression.Specification:Damper: GRIP2 w/ dual VVC (Variable Valve Control)Travel: 150 - 160mmOffset Options: 37mm / 44mm / 51mmWheel Size: 26", 27.5" & 29"Axle: 15QR x 110mm BoostSteerer: 1.5 TaperedColour: Gloss Orange & Gloss BlackUpper leg finish: Genuine Kashima Coat

At only 1380 grams this is the wheel that performance-obsessed cross-country racers dream of. Developed with input from top pro racers seeking a competitive advantage at World Cups and Olympics it features an ultralight full carbon 29” rim (360g) for fast acceleration and climbing without compromising stiffness and durability.Adaptive layup a specific carbon layup technology enabled us to handcraft these carbon rims with less material between the spokes. The spoke holes are reinforced with strategically positioned carbon layering in a process that minimizes weight without compromising stiffness and strength. A lighter rim means faster acceleration more efficient climbing and a more responsive feel on the trail. The external carbon layer features our new UD² construction for a distinctive look and added durability.Extensive field testing with our pro athletes determined that a 25mm inner width was ideal for a quick precise ride quality and optimized tire grip on fast racetracks. For more technical trails some preferred a 30mm width for added control so we created two options. It’s your choice and you can mix the two if you want. You could choose the Crossmax Ultimate 25 for the rear to boost acceleration and efficiency and the Crossmax Ultimate 30 for the front to add confidence and control on rugged single-track.The carbon rim is laced with 24 straight-pull double butted spokes (same spoke length throughout) two-crossed for maximum power transfer and enhanced vertical compliance. The new lighter Infinity hub design optimizes lateral stiffness and the spoke lacing maximizes power transfer.
