Bomber Z1 29 140 Grip Sweep-Adj Boost Fork

The original Bomber Z1 suspension fork was well ahead of its time, being the first to prioritize performance and durability over low weight. It was overbuilt and had astonishingly plush travel for the era, allowing riders to push the limits of what could be ridden on a mountain bike. Fast-forward 20 years and the Z1 returns, brought back to life by Fox Racing Shox. The Bomber Z1 29 140 Grip Sweep-Adj Boost Fork uses Fox's proven suspension technology wrapped in a bombproof chassis that is ideal for aggressive trail riding—all at a price point that leaves you with plenty of cash for epic riding trips with your friends.

The Bomber Z1 has 5.5in of travel, perfect for aggressive trail riding and all-day backcountry excursions. The plush travel soaks up nasty rock gardens and gnarled root sections with stunning composure, letting you rip technical trails with confidence. For extended climbs, the travel can be firmed or even locked out to improve pedaling efficiency.

The travel is granted by a FLOAT EVOL air spring. EVOL stands for "extra volume" and denotes the air spring's larger negative air volume, making the initial travel more sensitive for silky-smooth small-bump absorption. The mid-stroke is supportive, resisting brake dive when you grab the binders on tough descents. As you reach the end of the travel the bottom-out progression is smooth, preventing harshness on bigger impacts. You can even tune the progression of the air spring by adding or removing volume spacers, if needed.

Damping duties are handled by the FIT GRIP damper—a proven design known for durability and consistent performance. GRIP is an appropriate name as the damper's impressive sensitivity gives you unwavering traction on any trail. The adjustments are straightforward, simplifying setup so you can get out riding sooner. There is just one compression dial and one rebound dial. The compression dial combines high and low-speed compression in a sweeping design, meaning it turns from fully open to lockout with no clicks, letting you stop anywhere along the way once the setting feels right.

Marzocchi is known to have overbuilt forks, and the new Bomber is no exception. Stout 36mm stanchions and bombproof lowers prevent unwanted flex, ensuring the fork tracks well through repeated hits on rough terrain.
