◌Marzocchi Bomber Z1 Coil Mountain Bike ForksThis Mountain Bike Fork from Marzocchi features a tried and tested modern 36mm chassis, ideal for withstanding all the challenges from tough mountain bike (MTB) trails. Benefiting from Marzocchi's GRIP damper, it replaces the air-spring with a highly advanced coil system, for a lightweight spring that's made from tempered silicon Chromoly (CrMo) for exceptional durability and control, no matter what the terrain brings.Adjustable MTB Coil ForkReady for fast-paced adventures, this MTB fork is kitted out with an adjustment noise reduction system. This allows you to benefit from almost silent operation and external preload adjustment, which enables you to fine-tune the sag and suspension firmness. Compression and rebound can also be fine-tuned to set the fork up to suit your riding preferences and the trail conditions. One final highlight is the Marzochhi Bomber Z1 Coil Fork allows for alternative spring weights or inner spacers to be installed. This means you can customise its travel and performance even further.Features:Use: MTBFork Material: AluminiumFork Travel: 170mmChassis: 36mmAxle Included: YesAxle Type: 15 Quick Release x 110Damping: GRIP (compression + rebound)Lockout: YesOffset: 44mmSpring: Tempered Silicone-Chromium SteelSteerer: 1.5" tapered AluminiumStanchions: 36mm black AnodisedRake: 44mmWeight: 2.525g (starting weight complete fork)Manufacturer Part Numbers:Black 29", Travel 170mm: MAZ-912-01-091Black 29", Travel 160mm: MAZ-912-01-096Black 27.5", Travel 180mm: MAZ-912-01-099Black 27.5", Travel 170mm: MAZ-912-01-100Red 27.5", Travel 180mm: MAZ-912-01-101Red 29", Travel 170mm: MAZ-912-01-097Buy Marzocchi Forks from Chain Reaction Cycles, the World's Largest Online Bike Store.

Continuing the 15-year legacy of Double Barrel twin tube technology shocks from Cane Creek, Kitsuma is an incredibly adjustable rear shock designed to be incredibly easy to use. It caters to all varieties of rider styles, body types, and bicycle frame designs without the need for any internal changes. Kitsuma has expanded on the already wide range of adjustment from its predecessor while also reducing the number of external positions. These two advancements combine to create a discernible difference between each adjustment.Tool Free AdjustmentNo need to crane your neck under your bike while fumbling with tiny allen wrenches to make adjustments. DB Kitsuma sports completely tool-free adjusters that are ergonomically designed to be easily accessible and adjustable trail-side – giving riders the power of a pro-tune at their fingertips.Single Rotation Low Speed AdjustmentsGone are the days of counting clicks backward and forward to know where you are and make adjustments. The entire range of DB Kitsuma’s low-speed compression and rebound circuits are controlled within a single rotation, while the high-speed circuits are controlled within two rotations, allowing the rider to easily reference where they are within their adjustment at a glance. The rider has full control and a true sense for how their bike will handle in a variety of real-world scenarios thanks to DB Kitsuma’s large multi-indexed adjusters.Additionally, labels on the adjusters have been simplified to “soft” and “firm” for compression and “slow” and “fast” for rebound to better illustrate how the adjustment effects ride feel, and to give riders confidence to make trail-side adjustments.Finally, DB Kitsuma simplifies the tuning process by increasing the range of adjustment while reducing the number of external positions in each circuit – making each position more meaningful and discernible on the trail. All these improvements add up to a high-performance tuning experience that is incredibly intuitive and accessible.3-Position Climb SwitchDB Kitsuma is equipped with a single lever that switches the shock between three distinct modes, drastically affecting the shock’s feel and character. The new three position climb switch retains Double Barrel’s “Descend” mode it’s patented “CS” mode which provides a stable, yet responsive platform engineered to maximize traction and pedal efficiency while climbing over technical terrain and singletrack. DB Kitsuma also adds a new “Firm” mode. By utilizing a design that closes off the common bleed port, this third position excels at pedaling over long stretches of pavement or gravel roads on your way to the trail.FeaturesWeight: 585g (Air 210) | 471g (Coil 210 without spring),Damper :Double Barrel Technology refined into tool-free adjustment on all four circuits (LSC, HSC, LSR, HSR) ,Adjustment Range: Low Speed - 11 positions, fully indexed, single rotation. High Speed - 13 positions, fully indexed, two rotations,Climb Switch: 3 position CS lever,Shaft Diameter: 9.5mm (Coil and Air) for increased lateral stiffness,Maunfacturing: Hand built in Fletcher, NC.

Riders have been asking for it, Marzocchi heard the call and has proudly delivered.The new Z1 Coil builds on the legacy of the single crown fork that started the revolution way back in the 90s the O.G. Bomber Z1 Coil. Starting with the stout and proven 36mm chassis of the modern day Bomber Z1, the new Z1 Coil retains the renowned Grip damper but swaps out the air spring assembly for the most advanced coil spring system Marzocchi has ever made. At the heart of this new coil system is an ultra-lightweight tempered silicon-chromium steel spring (available in 4 spring rates to suit a wide range of riders) coupled with a noise management system for near silent performance, an integrated air assist for progressivity and bottom out control, and an external preload adjuster to dial in sag and firmness off the top. Travel can easily be changed in 10mm increments from 150-180mm (depending on wheel size) via included reconfigurable internal spacers.Key Features:Chassis: 36mm.,Travel:160mm, 170mm (29 only).,170mm, 180mm (27.5 only),.,Wheel: 27.5 or 29.,Axle: 15QRx110.,Damping: GRIP (compression + rebound).,Spring: Tempered Silicone-Chromium Steel.,Steerer: 1.5 Tapered Aluminum.,Stanchions: Ø36mm Black Anodized.,Rake: 44mm.,Colour: Matte Black or Gloss Red..

This race-ready mountain bike (MTB) fork is equipped with 35mm stanchions along with MRP's finest technologies to give all mountain and enduro racers exceptional front end suspension performance on the most rigorous of terrain conditions. Coming kitted out with Boost axle spacing, this model provides a stronger and stiffer construction, as well as more effective and precise handling as you tackle rock gardens, tree roots and debris. MRP Ribbon coil forks have also received updates including the ChocoLUXE internals and Norglide Bushings, which deliver less stiction and better-than-ever performance. Enduro MTB Fork with Coil Spring The Ribbon Coil gives you the spring tunability and stroke control previously found only with air, while giving you the supple linear spring curve, lower friction, longer service life and consistent feel that you get with a coil spring. Coil aficionados have dreamt of a fork that combines these advantages with the latest in chassis and damper technology. MRP has delivered with the Ribbon Coil. Also including tried and tested features like the PSST pressure relief valves, bladder-free EssenTTial damper utilising a low-pressure IFP, Outcast arch design and the acclaimed Ramp Control technology, this is the hard-hitting enduro fork to have. Technologies: ChocoLUXE Internals: - ChocoLUXE is a proprietary material utilised in the damper plug, damper seal, damper IFP, and damper support. It’s highly dimensionally stable, meaning that parts made from it are more consistent overall and less susceptible to change with exposure to temperature swings or humidity. It is also extremely low friction. Norglide Bushings: - Norglide Bushings from Saint Gobain are metal-reinforced, self-lubricating bushings with a layer of a low friction PTFE compound. They’re exceptionally smooth and durable. Reduced Friction: In addition to part updates, MRP also continued to refine its processes. In whole, these part and process changes have resulted in a 37% reduction in friction compared to first-generation Ribbon forks. Travel-adjustable coil spring system with preload adjustment and Ramp Control™ technology. New EssenTTial™ twin-tube, bladder-free damper utilising a low-pressure IFP. Outcast™ arch design with forward-facing weight reliefs to mitigate mud build-up. PSST™ pressure-relief valves that quickly and easily bleed off excess pressure in the lowers caused by elevation and temperature changes. "Boost" spacing and 35mm stanchions.
