Are ButterCups tunable?
No, ButterCups are only offered in one configuration, but they are tuned for real ride scenarios determined by in-field ride testing.
How do I know if my RockShox fork has ButterCups?
Forks with factory-installed ButterCups will have a sticker with the gold ButterCups logo on the lower leg.
Why are ButterCups called ButterCups?
Beacause they make your fork feel buttery smooth! Also, at RockShox, we call our trail and gravity fork team the Butter Wagon team, and they designed these little “cups”, hence: ButterCups.
What is the material that lives inside ButterCups?
ButterCups contain rubber pucks that absorb vibrations from the trail.
Do ButterCups allow for lateral compliance as well as vertical compliance in the bumpers?
No, the bushings and upper tubes arrest all the degrees of freedom except “vertical”. ButterCups aid in absorbing vibrations along the vertical axis.

The spring side ButterCups weigh 18.6 grams, and the damper side ButterCups weigh 20.4 grams. Together, both ButterCups add 39 grams.
