The new DebonAir is built to strike the perfect balance of what riders really want: butter-like small bump feel, increased air volume to add support throughout the travel and higher overall ride height for more confidence when things get steep. Includes air shaft assembly, ButterCup & seal head. Can be used to change travel. Compatible with Lyrik D1 (2023 ) models: FS-LYRK-SEL-D1, FS-LYRK-UFA-D2, FS-LYRK-ULT-D1, FS-LYRK-ULT-D3.
