Spring Type
  • DebonAir+ with ButterCups
  • FLOAT EVOL air spring: optimizes small bump sensitivity by increasing negative air spring volume; linear spring curve delivers plushness off the top, extra mid-stroke support, and more tunable bottom-out progression
    Damping
  • Charger 3 RC2 W/ButterCups
  • FIT GRIP damper cartridge with a coil-sprung, independent floating piston; GRIP allows excess oil to purge through specially designed ports at the top of the damper to maintain consistent damping and increase durability
    External Adjustments
  • High- and low-speed compression
  • Rebound
  • • Sweep Adjust compression damping (micro-adjust from Open to Firm)
    • Low-speed rebound damping: 10 clicks
    • Air spring pressure

    Miscellaneous
  • 2021 model year (RockShox model ID: FS-LYRK-ULT-C3)
  • Current RockShox model ID: FS-LYRK-ULT-D1
  • Updated highly tunable DebonAir air spring
  • Re-designed Charger 2.1 damper reduces hand fatigue and fights unwanted friction
  • Ultra-low friction SKF wiper seals provide long-lasting fork performance and improve overall suspension feel
  • Maxima Plush damping fluid reduces friction and silences damper noise
  • Sag gradients on upper tubes
  • Tire compatibility: 27.5" x 2.8" (27.5" Boost forks), 29" x 2.8" or 27.5" x 3.0" (29" Boost forks)
  • Offset: 37mm (27.5"), 42mm (29"), 44mm (27.5"), 44mm (29"), 46mm (27.5"), 51mm (29")
  • • 2023 version
    • E-Bike Chassis made specifically for the rigors of e-bikes with a stouter chassis and longer durability due to added material to strengthen critical areas; the design also uses tuning originally done for enduro use, which fits the needs of the E-MTB and overall e-bike uses
    • 6000 series aluminum stanchions
    • New crown with updated design and engineering for more steer tube overlap, improving durability and maintaining stiffness while dropping 20 grams
    • New lower leg arch with better frame clearance at full compression
    • Floating Axle creates perfect chassis alignment and eliminates unwanted friction between the upper and lower fork legs for smoother suspension movement throughout the range of travel
    • 37mm or 44mm offset
    • Quick release thru-axle
    • Optional: FOX 36/38 Mud Guard with sturdy 4-point direct-mount attachment
    • Optional: lower leg bleeders

    Lower leg air bypass channels:
    • Increased air volume within the lower legs reduces the amount of additional unintended pressure ramping
    • Lower leg bath oil circulates to the upper reaches of the legs, continuously lubricating the foam rings and bushings as the fork compresses and extends through its travel
