Product Detail

Revolutionary Rebound Tuning & Customization

1. 3-Gear Visual Tuning Window: Take full control of your ride quality. The innovative bottom viewing window lets you fine-tune the suspension behavior to your exact preference using a simple hex key:

Gear 1: Fastest rebound (ideal for high-frequency, rapid chatter).

Gear 2: Medium rebound (balanced for everyday all-terrain riding).

Gear 3: Slowest rebound (optimized for heavy impacts and big drops).

2. Watch it in action: Check out our embedded video to see the fluid linkage movement and adjustment guide.

High-Capacity Shock Isolation Geometry

1. Plush 37 mm Travel Linkage: Driven by a robust internal spring (73 mm effective spring length / 85 mm assembly), the linkage tracks along a smooth 36° arc to effectively isolate your spine from harsh trail thumps.

2. Generous 30 mm Setback: Designed with a pronounced 30 mm offset, this post expands your cockpit room, offering a relaxed and highly comfortable cruising posture for long-distance touring and gravel adventure.

Heavy-Duty Materials & All-Weather Protection

1. Forged 6061 Masterpiece: Built for ultimate structural durability featuring a precision-forged Alloy 6061 head paired seamlessly with a rigid, high-tensile 6061-T6 aluminum shaft (843 g for the 27.2 mm specification).

2. Included Neoprene Shield: Comes equipped with a tailor-made, sleek protective sleeve that seals the moving parallelogram pivots away from rain, mud, and dust.

3. Standard Fitment Diameters: Offered in a total length of 345 mm and available in the three most popular frame diameters: 27.2 mm, 30.9 mm, and 31.6 mm.
