Lyrik E1 Ultimate Charger 3.2 29in Boost Fork

What Our Gearhead® Experts Are Saying:

"The Lyrik E1 Ultimate Charger 3.2 29in Boost Fork is the most complete trail fork RockShox has built at this travel range. The Charger 3.2 RC2 with ButterCups genuinely changes how the fork feels over repeated square-edged hits and washboard chatter, and the Adjustable Bottom Out gives you a tuning lever that the Select simply does not have. ButterWagonTech keeping the bushings oiled throughout the service interval is the kind of engineering detail that pays off quietly over a full season of hard use."

The Lyrik E1 Ultimate Charger 3.2 29in Boost Fork represents the full expression of what RockShox set out to achieve with this generation of the Lyrik platform. Every technology decision made at the Ultimate tier exists to solve a specific performance problem, and understanding what each one does makes it clear why this fork sits at the top of the trail fork category.

The LinearXL air spring with Adjustable Bottom Out is the foundation. The LinearXL tuning delivers the now well-documented coil-like ride quality across the stroke, with genuine small-bump sensitivity off the top, progressive mid-stroke support, and controlled behavior through the final portion of travel. What separates the Ultimate from the Select is the Adjustable Bottom Out system, which gives riders a physical tuning dial to control how firm or progressive the end-stroke feel becomes. This is not a token feature. On technical terrain where bottom-out frequency and character vary significantly by trail and rider weight, the ability to tune end-stroke behavior independently from overall spring rate is a meaningful advantage.

The Charger 3.2 RC2 damper introduces ButterCups technology, a system that isolates and absorbs high-frequency trail chatter before it reaches the rider's hands and arms. RockShox rates the reduction at 20 percent of high-frequency inputs, and the effect on rider fatigue over long days is tangible in a way that becomes most apparent on extended rides over rough terrain. The damper also features a numbered high and low speed compression adjuster that starts at zero and builds from there, making trailside setup genuinely fast and easy to communicate and replicate across different conditions or bikes. Rebound and compression tunes have been specifically matched to the LinearXL air spring character for virtually silent, cohesive performance across the full range of adjustment.

ButterWagonTech, exclusive to the Ultimate tier, addresses a problem that most riders do not think about until they notice fork performance degrading between services. By maintaining a constant supply of oil to the upper tube bushings throughout the entire service interval, the system ensures that the fork delivers the same smooth, low-friction feel at the end of a season as it does at the beginning. Combined with low-grab SKF wiper seals and Maxima 920 blended 15-weight oil across the rest of the system, the Lyrik E1 Ultimate Charger 3.2 29in Boost Fork is engineered to stay at its performance ceiling longer and more consistently than any trail fork in its class.
