RockShox Lyrik D1+ DebonAir+ Buttercup Air Spring Upgrade Kit 160mm

The RockShox Lyrik D1+ DebonAir+ Buttercup Air Spring Upgrade Kit 160mm brings RockShox's latest air spring technology to compatible Lyrik forks. The DebonAir+ system is designed to improve small-bump sensitivity and mid-stroke support, while the Buttercup feature — a secondary air chamber built into the bottom of the air spring — is intended to reduce harsh bottom-out forces without sacrificing progressive ramp-up. The result is a more supple, controlled feel across rough terrain and high-speed compressions alike.

Designed as a direct upgrade for D1+ generation Lyrik forks, this kit swaps in at 160mm travel. If your fork has been feeling harsh at the end of its stroke or losing sensitivity after extended use, replacing the air spring assembly is one of the most effective single interventions available.

• Travel: 160mm
