The RockShox Pike Boost 27.5" suspension fork for trail bikes comes in the Ultimate configuration with Charger 3 RC2 damper and DebonAir air spring, which are 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.
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, adjusting 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 behavior
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
Fork crown outer diameter: 58 mm
Fork crown light, milled, and anodized
