The Lyrik E1 Ultimate Charger 3.2 29in Boost Fork raises the bar for trail fork performance
What Our Gearhead® Experts Are Saying:
"I have been putting serious miles on the Lyrik E1 Ultimate Charger 3.2 29in Boost Fork across a mix of all-day epics and bike park laps, and it handles both without hesitation. The ButterCups technology is not marketing language, the reduction in high-frequency chatter is genuinely noticeable over a long day in the saddle, and the numbered compression adjuster made setup faster and more intuitive than any fork I have dialed in before. The ABO system adds a level of end-stroke tuning that the Select version simply cannot match."
Most trail forks ask you to make a trade, climbing performance for descending capability or small bump sensitivity for end-stroke control, and the RockShox Lyrik E1 Ultimate Charger 3.2 29in Boost Fork was engineered to refuse every one of those compromises. Whether the route demands a punishing climb followed by a technical chunder descent or a full day of rowdy singletrack with no clear end in sight, this fork stays composed, smooth, and utterly confidence-inspiring from the first pedal stroke to the last.
The new LinearXL air spring with Adjustable Bottom Out takes the coil-like ride feel of the platform and adds genuine tunability at end-stroke, letting riders dial in exactly how the fork behaves when things get deep. The Charger 3.2 RC2 damper brings ButterCups technology to the equation, blocking 20 percent of high-frequency trail chatter to reduce hand and arm fatigue over long days in a way that becomes most apparent at hour four or five when lesser forks start to take a toll. ButterWagonTech, exclusive to the Ultimate tier, maintains a constant supply of oil to the bushings throughout the entire service interval, so the fork stays smooth and consistent whether it is fresh off a service or deep into a season of hard use.

The Essentials Of Versatility

Stay Composed
Lyrik’s balanced chassis delivers in both directions, keeping riders fresh and in control.
Enable The Air Spring
LinearXL is a whole fork approach to air spring design, delivering predictable position-sensitive control.

The Perfect Setup Is Personal
The all-new Lyrik features adjusters that visibly indicate settings and make fine-tuning simple and intuitive.
Put A Lyrik On It
Versatility Is Predictability
LinearXL provides a position-sensitive linear curve. That means as you move through the travel, the rate at which the fork increases force never changes—delivering predictability.
Independent Bottom Out Control
Adjustable Bottom Out (ABO) lets you dial in exactly how much bottom-out support you want, while keeping the rest of the stroke consistent and predictable.

Linear XL AirAnnex
The AirAnnex on Lyrik’s lower leg increases the lower leg air volume, which reduces the air-spring progressivity and speed-sensitivity inherent to traditional lower leg designs.

Stanchions That Breathe
Strategically placed breather holes in the stanchions allow for the lower leg air volume to increase as the fork goes through its travel.
Charger 3.2: Speed Sensitive & Silent
Re-tuned for the unique position-sensitivity of LinearXL, Charger 3.2 delivers speed-sensitive control with fully independent High Speed and Low Speed Compression damping.
Exactly The Sweet Spot

DH-Level Stiffness
TorqueCap dropouts give Lyrik torsional stiffness on par with a 20mm downhill axle. All from a standard, lightweight 15mm Maxle. For an improvement in precision and steering response riders absolutely feel.
A Chassis For Serious Versatility
Lightweight without forgetting its long-travel roots, designed to make easy work of the whole mountain. Lyrik’s chassis features a fully re-engineered, buttressed lower leg built to handle every hit, at a weight that’s not a chore to pedal.
ButterWagonTech
ButterWagonTech is a proprietary matrix of divots on Lyrik stanchions that works to carry (or ‘wagon’) fresh layers of our exclusive, high-density Maxima oil to the bushings with every millimeter of travel. Unparalleled in design and function, ButterWagonTech sets a new benchmark for sensitivity.
ButterCups Vibration Reduction
ButterCups effectively isolate the air spring and damper shafts from chatter, cutting high-frequency vibration by up to 20%. Riders feel the difference, whether striving for a PR or tackling an all-day epic. Less arm pump. Less hand fatigue. More fun all day.

Exclusive Seals for Sensitivity
Most wiper seals deflect into the upper tube when the lower leg pressurizes, creating more friction. To solve for this, we worked with SKF to develop an exclusive design that cleans the dirt without grabbing the upper tube, increasing sensitivity deep in the travel.
