Product details:

model Zeb forks. Debonair+ Air SpringBy focusing on refining the shape of the spring curve, RockShox created an air spring thats more plush off-the-top, with a supremely supportive mid-stroke and improved end-stroke ramp up. They zeroed in on details to improve small bump absorption to be extremely reactive over every inch of trail and added mid-stroke support allowing the fork to sit higher in travel and utilize every millimeter of travel. The new DebonAir+ offers a supreme ride feel and consistency you can trust. ButtercupsLittle 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 measurably eliminate trail chatter by on average 20%. Proven by data acquisition over thousands of trail miles and confirmed by riders.
