Bomber Z1 29 170 Grip Sweep-Adj Boost Fork
The original Marzocchi Bomber Z1 fork helped spark the freeride revolution by being the first to truly prioritize performance and durability over saving weight. The fork was overbuilt and had absurdly plush travel for the time, helping push the limits of what could be ridden on a mountain bike. Fast-forward 20 years and the Bomber Z1 returns, brought back to life by Fox Racing Shox and their proven suspension designs. The Bomber Z1 29 170 Grip Sweep-Adj Boost Fork offers plush travel and a sturdy chassis, with proven damping and air spring technology from Fox. It's ready to slay technical all-mountain lines and charge enduro stages with confidence, all while leaving you enough cash for epic riding trips and race entry fees.
The Bomber Z1 has 6.7in of plush travel, making it well-suited to steep, technical trails and the rigors of enduro racing. This amount of travel lets you charge into chunky rock gardens with confidence and composure. Or maybe you'd rather just gap over the rocks instead. With this much travel it's your choice. For extended climbs, the travel can be firmed up or even locked out to improve pedaling efficiency.
The travel is provided by a FLOAT EVOL air spring. EVOL stands for "extra volume" in reference to the increased negative air volume, making the initial travel more sensitive for buttery-smooth small-bump compliance. The mid-stroke is supportive to help resist fork dive when you grab the brakes on steep descents. As you near the end of the travel the bottom-out progression is smooth, preventing harshness on larger impacts. The air spring's progression can be tuned by adding or removing volume spacers, if needed.
Damping duties are handled by the FIT GRIP damper—a proven design known for durability and consistency. GRIP is an appropriate name as the damper offers impressive sensitivity, providing unwavering traction on blown-out enduro stages.
The adjustments are uncomplicated, 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.
With a long travel fork like this it's important to have a stiff chassis. Stout 36mm stanchions and bombproof lowers help prevent unwanted flex, ensuring the Bomber Z1 tracks well over the roughest terrain.
