The RockShox Lyrik Ultimate with Charger 3.2 RC2 is the top-tier version of RockShox's Lyrik trail fork - a 29-inch, 160mm travel fork built for riders who demand both descent capability and pedalling efficiency on all-day trail rides. The Ultimate designation brings ButterWagonTech and the Charger 3.2 RC2 damper to the Lyrik platform - features reserved exclusively for the top tier that deliver a level of smooth, consistent performance across a full service interval that lower-tier Lyrik versions cannot match.
This is the 160mm travel configuration with a 44mm offset, 15x110mm Boost thru-axle, and tapered steerer in Gloss Black. The 576mm axle-to-crown length and 28.6mm stem clamp diameter are standard measurements for a 29-inch 160mm trail fork. Maximum tyre width accommodation is 70mm, and the fork accepts a full fender without tyre clearance compromise thanks to the lower arch's design. Post Mount brake interface is rated for a 180mm rotor.
The tapered steerer requires a frame with a tapered head tube - confirm your frame's head tube specification before purchase.
The Linear XL air spring is the same spring system used in the Super Deluxe Ultimate rear shock - delivering a consistent, predictable, coil-like ride feel that is supple at the top of the travel, supportive through the midstroke, and backed by Adjustable Bottom Out (ABO) for confident end-stroke control. The coil-like character is RockShox's description of the Linear XL's progressive feel - smooth and responsive rather than harsh or spiked in its response to trail inputs.
Adjustable Bottom Out (ABO) allows the end-stroke feel to be tuned - adjusting how the fork behaves in the final portion of its travel to prevent harsh bottom-out impacts while maintaining full travel use. ABO provides a configurable hydraulic cushion in the last portion of travel that complements the air spring's volume tuning for a fully dialled end-stroke character.
ButterWagonTech is the feature exclusive to Ultimate-level RockShox forks that most directly affects long-term performance consistency. Standard forks rely on the fork's oil bath to lubricate the bushings - a system that can leave bushings inadequately lubricated as the oil level drops between services. ButterWagonTech uses a dedicated oil delivery system that maintains a constant supply of oil to the bushings throughout the entire service interval, reducing friction and maintaining smooth, consistent fork performance from the first ride after service to the last ride before the next one.
The Charger 3.2 RC2 damper provides both Low Speed Compression and High Speed Compression adjustment on the same control bezel - a numbered compression adjuster that starts at zero for intuitive setup from a known reference point. The HSC and LSC tunes are specifically matched to the Linear XL air spring's characteristics for virtually silent operation that keeps the rider focused on the trail rather than on fork noise.
ButterCups technology is integrated into the upper tubes of the Lyrik Ultimate - elastomeric cups that block 20% of high-frequency trail chatter vibration from reaching the rider's hands and arms. This reduction in high-frequency vibration reduces hand and arm fatigue across long trail rides where sustained vibration accumulates as fatigue even when individual impacts are not large enough to be consciously noticed.
The wider Lyrik crown boosts lateral stiffness for improved steering precision and climbing efficiency, with post-forging machining inside and out adding dimensional accuracy without adding weight. The lower arch delivers increased stiffness for precise handling under load - maintaining composure during aggressive cornering and heavy braking - while retaining full tyre clearance even with a full fender installed.
ButterWagonTech is RockShox's dedicated oil delivery system that maintains a constant supply of oil to the fork's bushings throughout the entire service interval. Standard forks rely on oil bath lubrication which degrades as oil levels drop between services, increasing friction over time. ButterWagonTech maintains consistent low-friction performance from the first ride after service to the last - a feature reserved exclusively for Ultimate-level RockShox forks.
ButterCups are elastomeric vibration damping elements integrated into the upper tubes that block 20% of high-frequency trail chatter before it reaches the rider's hands and arms. This reduction in sustained vibration reduces hand and arm fatigue over long trail rides where high-frequency inputs accumulate as fatigue even when individual impacts are small.
ABO is a hydraulic end-stroke control system that creates a configurable cushion in the final portion of the fork's travel - preventing harsh bottom-out impacts while maintaining full travel use. The adjustment allows the end-stroke feel to be tuned from firm to softer depending on rider preference and terrain demands.
The fork uses a tapered steerer - requiring a frame with a tapered head tube. Confirm your frame's head tube specification before purchase as tapered and straight steerers are not interchangeable.
The fork uses a Post Mount brake interface rated for a 180mm rotor. Confirm your brake caliper uses Post Mount compatibility. A rotor is not included and must be sourced separately.
