RockShox Lyrik Ultimate RC2 DebonAir+ Boost 29" Suspension Fork

The RockShox Lyrik Ultimate RC2 DebonAir+ Boost suspension fork for 29" wheels let you master every trail

The RockShox Lyrik Boost 29" suspension fork offers enough travel for all those determined to take on all-mountain to enduro trails, and comes outfitted with Ultimate equipment with Charger 3 RC2 damper and DebonAir+ air spring. These are each supported by ButterCups. The completely independent adjustment of high and low-speed compression damping enables precision tuning and saves you from having to calculate the interplay. The DebonAir+ air spring impresses with excellent response and confidence-inspiring control. Another highlight are the ButterCups, which absorb 20% of those small but incessant vibrations that make life difficult for your arms and hands on long, bumpy trails. The Ultimate bushings are 53% longer than the previous model and have a higher overlap area for low-friction operation. Pressure relief valves allow the air pressure in the immersion tubes to be easily adjusted to the environment.

Guidelines for Replacing E-bike Components:

Before you replace components on your e-bike, please read through the guidelines for component replacement for CE-marked e-bikes/pedelecs with pedal assistance.

Features:

• Charger 3 RC2 damping with fully independent adjustment of low and high speed compression through IFP design enables precise tuning
• 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 at the same time stands higher in the suspension travel
• pressure relief valves release excess air pressure in the immersion tubes at the push of a button, adjustment of the air pressure to the environment
• reduced friction due to longer Ultimate bushings with higher overlap than the previous model
• 35 mm stanchion tube diameter for a good ratio of stiffness and low weight
• low-friction SKF wiper seals for high durability and good suspension behaviour
• with Maxima Plush Dynamic Suspension Lube for low friction and good durability
• crown adjust
• torque cap dropouts for increased stiffness
• with screw-on torque cap adapters for simplified use with standard end caps
• also suitable for e-bikes
• fork crown outer diameter: 59 mm
• fork crown light, milled and anodised
