Marzocchi Bomber Z1 Coil 27.5" Boost Suspension Fork

The Bomber Z1 Coil 27.5" Boost suspension fork by Marzocchi offers legendary ride quality in a modern chassis

With the Bomber Z1 Coil, Marzocchi offers a suspension fork with a specially hardened, super-light silicon-chromium steel spring. The preload of the spring is done by the top cap and is purely there to adapt the sag (negative spring travel) to the rider's weight, but has no influence on the spring rate. In addition to the typical M-crown design, the fork offers a stanchion tube diameter of 36 mm, a travel of 160 mm to 180 mm and Grip damping with adjustable compression and rebound. All forks are supplied with a medium coil.

Grip:
Inspired by motocross technology, the Grip damper cartridge works with a spring-loaded, independently operating floating piston. Grip technology allows excess damping oil to flow through ports at the top of the damper, ensuring even damping and increasing durability.
