Marzocchi Bomber Z1 Boost Mountain Bike ForksEngineered for the most aggressive MTB (mountain bike) riders, the Bomber Z1 Boost Mountain Bike Fork is ready to tackle the toughest all-mountain (AM) and enduro routes. This adjustable MTB fork is tough and rigid thanks to its sold alloy composition. Marzocchi has also included black anodised stanchions to ensure you enjoy a smooth ride, whatever the terrain throws at you.MTB Fork with EVOL Air SpringReady to carve up the trails, this Boost-compatible fork is equipped with an EVOL air spring. It works by increasing negative air spring volume to specifically provide optimum small bump sensitivity. This allows you to enjoy its smoother performance as you blast over the rock gardens, tree roots and debris at speed.Adjustable GRIP DamperKeeping your ride under control, this fantastic trail-ready fork is also kitted out with an adjustable GRIP damper. This cartridge style damper allows you to fine-tune its compression and rebound to maintain a consistent riding experience across unpredictable surfaces. Another benefit of the Marzocchi Bomber Z1 Boost Fork’s damper is its compression adjustment ranges from open to lockout. This allows you to ride in an open or locked position depending on the terrain.Features:Material: Alloy Spring: EVOL air spring Damper: GRIP Adjustments: Compression speed, rebound speed Lockout: Yes Axle: 15x110mm thru axle (Boost) Thru Axle Included: Yes Steerer Tube Size: Tapered 1.1/8" to 1.5" Stanchion Diameter: 36mm Use: All-Mountain (AM), Enduro Adjustable Travel: No Offset: Separate 44mm and 51mm optionsBuy Marzocchi Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

This model of the legendary Fox 36 receives an update in the form of a revised crown design that's engineered with more steerer tube overlap. This improves its durability and maintains stiffness while dropping 20 grams. Updated Crown Lighter by 20 grams, while increasing steerer-tube overlap at the CSU, the updated crown design improves durability while our engineering maintains stiffness and drops weight. Kabolt X Axle Kabolt X is a lightweight bolt-on floating axle to shave grams and increase torsional stiffness via a sleeveless, it features a single-sided pinch bolt design. Lower Leg Bypass Channels Increasing air volume within the lower legs reduces the amount of additional unintended pressure ramping. Lower leg bath oil also circulates to the upper reaches of the legs, continuously lubricating the foam rings and bushings as the fork compresses and extends through its travel. Lower Leg Bleeders Allows for atmospheric pressure equalization for better fork performance, allowing full travel to be achieved and increasing small bump sensitivity and responsiveness. Lower Leg Arch Our new lower leg design pulls out all the stops, shaving every possible gram while making sure not to compromise the stiffness or strength requirements of modern enduro and gravity-style riding. Grip2 Damper Unparalleled ride quality and ultra-precise adjustability. Allows for external fine-tuning of suspension performance thanks to our patented Variable Valve Control (VVC) technology. Float EVOL Air Spring Optimises small bump sensitivity by increasing negative air spring volume. Its linear spring curve delivers plushness off the top, extra mid-stroke support, and a more tunable bottom-out progression. Technologies: Factory Series: “Factory” says it all – feature-packed and designed to exceed the demands of Factory-level riders. What we sell is what they race. Factory Series products feature slippery smooth, ultra-durable Genuine Kashima Coat. Adjustments: Three on-the-fly compression damping positions Open, Medium, Firm. Additional low-speed compression (Open mode adjust) 22 clicks. Low-speed rebound 10 clicks. Floating Axle: Floating axles might look similar to other axles, but in fact they offer a distinct performance advantage due to their unique ability to match the exact width of the fork’s wheel mounting surface precisely to the front hub flange spacing, thus creating perfect chassis alignment and eliminating unwanted friction between the upper and lower fork legs. Floating axles provide much smoother suspension movement throughout the entire range of the fork’s travel, notably improving sensitivity and overall ride quality. The all-new 36 and 38 come equipped with a new quick-release lever operated patent-pending floating axle system, combining the benefit of a floating axle with the ease of a tool-free quick-release. With this system, spacing is locked in via a floating sleeve, allowing repeated front wheel removal and reinstallation while maintaining perfect fork alignment. Floating sleeve positioning comes preset from the factory so if you are unsure of how to operate the floating axle system or simply don’t want to bother with it, you can just install the front wheel and get on with your ride. Lower Leg Bypass Channels: As a fork compresses, the air volume within the lower legs decreases, increasing air pressure. The more the fork compresses, the more pressure increases. This effect can have the unintended consequence of preventing full travel from being achieved. Fox Suspension's lower leg channels help alleviate this issue by dramatically increasing air volume within the lower legs and thereby reducing the amount of additional unintended pressure ramping. Another benefit of these channels is that lower leg bath oil is circulated to the upper reaches of the lower legs, continuously lubricating the foam rings and bushings as the fork compresses and extends through its travel. Bleeders: Fox Suspension's lower leg bleeders allow for atmospheric pressure equalization at the simple press of a button. Pressure build-up in the lower legs dramatically decreases fork performance, preventing full travel from being achieved, and diminishing small bump sensitivity and responsiveness. Lower Leg Arch: Stiffness-to-weight is the ultimate metric for bicycle design. Engineers invest countless hours poring over every ounce of material in an effort to optimize this critical ratio. Fox Suspension's lower leg design pulls out all the stops, shaving every possible gram while making sure not to compromise the stiffness or strength requirements of modern enduro and gravity style riding. Modern frame designs and geometry trends require modern suspension design solutions. The arch design of the all-new 36, 38, and 40 are designed to pair perfectly with modern Enduro and Downhill bikes. Head tube profiles have grown larger and larger, and fork offsets shorter and shorter. Fox Suspension's new arch shape takes this need into account by jutting forward to provide ample headtube clearance at full compression. State-of-the-art computer modelling techniques helped us to create an organic lower leg shape that optimizes stiffness with the absolute minimal amount of material.
