This shock provides a more delicate damping system to handle both small and big impacts, with improved durability. It offers adjustable rebound, compression, preload, and air pressure. The shock body is dark hard-anodized AL-7075, featuring a hard chromed 12 mm shaft designed to withstand rugged off-road terrain. Suitable for AM, FR, and DH riding styles, this option aims to deliver reliable performance on demanding trails.

Coil springs are sold separately from the Vivid and Kage shocks, allowing riders to select the appropriate weight rating for their riding style and bike setup. Availability in various sizes helps tailor spring rate to rider weight and terrain.

Buying Guide: Key Purchase Considerations
- Ride style and terrain: Choose a shock tuned for your typical riding—enduro, downhill, or all-mountain—to optimize damping and support.
- Spring type and weight: Coil springs provide stable support for heavy impacts and aggressive riding, while air springs offer tunable SAG and progressive feel for lighter riders or mixed terrain.
- Eye-to-eye length and stroke: Verify the exact mounting geometry on your bike. The 7.875 x 2.0 standard is common, but exact fitment depends on frame design and linkage.
- Adjustability: Look for shocks with rebound, compression, preload, and air pressure adjustments to dial in feel under different conditions.
- Durability and materials: Anodized bodies (AL-7075, AL-6061) and chromed shafts improve longevity in muddy or dusty conditions.
- Maintenance and compatibility: Some options require specific service kits or professional setup. Confirm compatibility with your existing components and service interval expectations.
- Weight considerations: Heavier shocks can improve durability and control but may affect bike weight and pedaling efficiency; balance with rider preferences.
- Warranty and support: Reputable brands typically offer robust warranties and replacement parts, which helps long-term ownership.
