Rock Shox has introduced the proven damping performance of the popular Monarch series in a chassis with metric dimensions. Increased bushing overlap, a new bushing design and a new wiper seal reduced friction and increased durability. Now they've changed the inner surface to improve lubrication and speed piston movement - further friction reductions that keep the tires firmly on the ground. Again, the result is deluxe. - Details: - Highly tunable DebonAir spring provides a spiraling, consistent feel throughout the ride - Dual piston damper design - Energetic wear band design - Provides tighter lockup and keeps the bike up on the ride - Compression adjustment in 3 positions - Type / Range of Use: MTB Spring System - Type: Air Damping - Adjustability: Compression Damping - Installation Length (mm): 170 - Stroke: 35 mm - Rebound: yes.
