4 independent, external settings for custom tuning: rebound damping, TST compression damping, IFP air pressure, and main chamber air pressure (updated for MY09 with a carbon-wrapped air canister). TST Terrain Selection Technology: 180-degree, on-the-fly lever for adjustable compression damping offering 'virtual lockout'. High volume linear air spring for lightweight FR/AM performance. Nickel-coated alloy air canister with alloy shaft, plus a piggy-back reservoir with IFP (internal floating piston) bottom-out resistance. Sized by travel/stroke and eye-eye measurements (note: not guaranteed to fit all bikes). *Mounting hardware sets sold separately (2 mount sets required per shock: 1 for each eyelet).
