Product Description 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 adjusted via the top cap and is purely designed 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.
