Charge the trail with total confidence in the Lyrik E1 Select 27.5in Boost Fork
What Our Gearhead® Experts Are Saying:
"I ran the Lyrik E1 Select on a rowdy enduro loop with plenty of chunk, and the LinearXL air spring tracked everything without feeling harsh or unpredictable through the rough sections. The Delta RC damper controls are dead simple to adjust trailside, and I had compression and rebound dialed in within two runs. For riders who want dependable performance without getting lost in a tuning rabbit hole, this fork punches well above its price."
Some trails do not ask politely before they get steep and loose, and the Lyrik E1 Select 27.5in Boost Fork was made for exactly those conversations. Rock Shox designed this fork around the new LinearXL air spring, a system that keeps the ride feeling consistent and predictable from the top of the stroke all the way through to the bottom-out control, which keeps things tidy when the terrain gets truly nasty.
The new Delta RC damper handles compression and rebound through intuitive external controls that are easy to reach and adjust without stopping the ride. Low-speed compression shapes how the fork handles braking bumps and roll-over forces, while independent rebound tuning lets you set the return speed to match your trail and your style. A Fast Black stanchion finish on the 35mm legs reduces friction and extends seal life, and the included integrated fender mount keeps roost out of your face on wet days. With e-bike approval and Boost 15x110mm spacing, the Lyrik E1 Select fits a wide range of modern trail and enduro builds.

Jack of all trades, master of confidence.
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.
