Technology

Cutting-Edge Components for Electric Bike Drivetrains

Maxima Plush Fluid

Developed with the world's fastest racers, on the world's toughest circuits. Maxima Plush Fluid is designed to protect from suspension wear, reduce friction, and silence damper noise while maintaining a consistent feel in all temperatures.

SKF Seals

Everyone loves a good collaboration, which is why we’ve been working with SKF, the world’s highest-performance seal manufacturer, for over 5 years. Together we’ll provide ultra-low friction wiper seals, less fatigue, and unmatched suspension feel, all while keeping the dirt where it belongs- because no one wants dirt in there.

ButterCups

Low amplitude, vibration reducing material pucks... but we like to call them ButterCups. ButterCups block 20% of unwanted “trail chatter” before it reaches your hands. The gold housings on the end of the damper and air spring hold two rubber pucks that absorb the high frequency vibrations before they travel through the fork and into the handlebar. ButterCups reduce overall hand and arm fatigue and will leave you feeling fresh with more control over the trail.

DebonAir+

DebonAir+ is built to strike the perfect balance of what riders really want: butter-like small bump feel, increased support throughout the travel, and higher overall ride height for more confidence when things get steep.

Charger 3

Scrap everything and start from scratch. It took a fresh set of eyes to produce what became the Charger 3 damper. Let’s see what we can do, where we can go. The result gives way to a new era of riding, where the decision between adding more damping and sacrificing your hands to a harsh ride doesn’t exist.

BUTTERCUPS

STRIKING GOLD

Low amplitude, vibration-reducing compliant material pucks... but we like to call them ButterCups. Good things come in small packages. ButterCups are no exception. These tiny nuggets are worth their weight in gold. An application dreamt up by RockShox engineers’ never-ending quest for performance that empowers you with the confidence to ride safer, faster, and harder than ever before. ButterCups are all about boundary-breaking capability.

THE PROBLEM YOU NEVER KNEW YOU HAD...

Trail Chatter. We’re talking about the frequency domain—finding a solution to block the high-frequency vibrations that reverberate from the trail, through your fork, straight to your white-knuckled hands. Think fast sections full of roots or small rocks. ButterCups take the initial sting off to greatly reduce the chance of fatigue.

THE GOLDEN SOLUTION

Two little gold-packaged rubber pucks live at the end of the damper and air spring shafts and fit into the lower leg of the fork. Similar technology is found in off-road vehicles, chainsaws, and most devices that transfer high-frequency vibrations into the hands and arms of the user. Like a rubber mount on the handle of the chainsaw, ButterCups dampen high-frequency vibrations before they hit your hands and arms and lead to an early end to an otherwise good day.

How we did it…

Great things never come easily. Nailing down high-performance vibration damping took meticulous lab and field testing. Different durometers (the measurement of rubber hardness). Different geometries. Dozens of iterations. All to find that “just right” Goldilocks solution—durable enough to withstand trail beating after trail beating, while still being soft enough to do their job.

The Result?

ButterCups measurably eliminate trail chatter by 20%. Proven by science and technology, confirmed by riders and thousands of trail miles. Riders gain more stamina to hold on longer while having the confidence gained in knowing that the front-end is tracking precisely with the trail—you’re safe to push the limits harder than ever before.
