Marzocchi Bomber Z1 27.5" Boost Suspension Fork

The Bomber Z1 27.5" Boost suspension fork by Marzocchi returns

With the Bomber Z1 27.5" Boost suspension fork, Marzocchi relies on a well-known design with its double crown fork and the typical M fork crown. The EVOL air spring increases the air chamber volume of the negative chamber for a smoother response. The progression of the fork can be further refined with the volume spacer click system and adjusted according to your own wishes. Grip Sweep damping with adjustable rebound and a continuously adjustable low-speed compression stage is also used. For the Bomber Z1 27.5" , Marzocchi relies on black 36 mm thick stanchions and a travel of 150 mm to 180 mm. Perfect for your Enduro adventure.

Technology:

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.

Float Air Spring:
Patented air transfer port system: The float air suspension system reduces the breakaway torque and thus offers a highly sensitive fork and full comfort even with small impacts. And that for every type of rider and at the most varied air pressure. Similar to the Float suspension rear shocks, the Float suspension system is characterised by a positive and a negative air chamber, which automatically balance each other out when riding.

Air Volume Spacers:
The Float air suspension of the forks can be finely adjusted by using volume spacers to adjust the suspension elements more progressively or less progressively. This allows the rider to fine-tune the suspension exactly to their needs.
