Features:

• 29" -Enduro fork with fine adjustability and improved damping for precise control
• Charger 3.1 RC2 damping with independent settings for low and high-speed compression, with less compression damping in the open LSC position and more support in the closed HSC position than previous generation
• ButterCups for smooth riding absorb 20% of lighter, high-frequency vibrations and thus prevent fatigue
• DebonAir+ air spring with more volume than DebonAir absorbs smaller bumps even better and maintains a higher position in the travel
• Reduced friction due to longer Ultimate bushings with higher overlap than the previous model
• 38 mm stanchion tube diameter for more stiffness and safety
• Low-friction SKF wiper seals for high durability and good suspension behaviour
• With Maxima Plush Dynamic Suspension Lube for low friction and good durability
• Torque cap dropouts for increased stiffness
• With screw-on torque cap adapters for simplified use with standard end caps
• Also suitable for e-bikes
