The Bomber Z1 is Marzocchi's no-fuss all-mountain fork: a stiff 36mm chassis, an updated Rail damper and an air spring you set once and ride. Set your sag, click in your rebound and point it down the hill.
Highlights
- 36mm stanchions for steering precision and traction when things get rowdy
- Pressure-balanced Rail damper with a 2-position sweep compression lever and rebound adjust
- Air spring, tunable with volume spacers
- 29in wheels, 44mm rake and a 15 x 110mm quick-release axle
- 150mm or 160mm travel
Rail damper: less fiddling, more riding
The updated Rail damper is pressure balanced and keeps adjustment simple: a 2-position sweep lever locks out for climbing and opens up for descending, with the positions in between for fine-tuning, plus a rebound knob under the damper-side leg. Marzocchi publishes starting air pressure and rebound clicks by rider weight, so setup takes minutes.
An air spring you can tune
Add a few psi for bike park days or harder charging, and add or remove air volume spacers to change mid-stroke and bottom-out support. Maximum air pressure is 120 psi.
Compatibility & fit
1.5in tapered aluminium steerer (39.8mm crown race), 15 x 110mm quick-release axle and a 180mm post mount; Marzocchi's maximum rotor size for the Bomber Z1 is 230mm. Check your head tube, front hub and brake setup before you order. Fitting is a separate workshop service. Tune Cycles is an authorised Fox service centre (Fox owns Marzocchi), so our Marrickville workshop can cut the steerer, install the crown race, fit and set up your fork.
