Hope Tech 4 Trial Zone No.9 Brake - No RotorBenefitting from an updated lever shape, this mountain bike (MTB) hydraulic disc brake provides greater ergonomics for a superior mechanical advantage when braking on your trail adventures. In addition, it also boasts a 30% pressure increase when compared to its predecessor the Tech 3 brake, meaning you can enjoy increased power. Another highlight is its tool-free bite point and reach adjustments for fine-tuning it to perfectly match your hand size as well as the terrain conditions.MTB Hydraulic Disc Brake with Adjustable Trial AnchorThe Tech 4 Trial Zone builds on the brand's 25+ years' experience designing and manufacturing hydraulic brake systems. The Tech 4 uses revised internal sealing for reduced friction and the pivot spins on roller bearings, allowing the spring rate to be reduced. The lower spring rate in turn gives a lighter lever action, reducing rider fatigue and keeping the legendary feel and modulation.Tool-Free Reach AdjustDesigned for simplicity, Hope has kitted out this mountain bike (MTB) hydraulic disc brake with a tool-free reach adjustment and bite point. This means that you can easily fine-tune the distance between the lever blade and your handlebar for a more customised braking feel that matches your hand size as well as your riding style. Coming complete with a range of performance-enhancing technologies, the Hope Tech 4 Trial Zone No.9 Brake - No Rotor is an ideal choice for powerful and consistent braking operation on every trail adventure.Features: Use: Mountain Bike (MTB) Increased power versus Tech 3 Hinged clamp reducing weight and ergonomics Shifter integration improved for more adjustability Tool-free bite point and reach adjustments Two huge 25mm Aluminium pistons offer great power and stiffness Rigid CNC'd one piece caliper Designed to work with Hope's Trial Zone rotors for optimum performance Rotors Included: No, available separately Single or Pair: SingleTechnologies: 30% pressure increase compared with the Tech 3 brake. Hinged clamp design to reduce weight and reservoir area increased to lower overall stack height. Shifter integration has been improved and now offers 30° of angle adjustment as well as neater packaging and compatibility with the latest shifters. Lateral adjustment on both sides of the master cylinder is also possible to give a wide range of lever position options. The Tech 4 retains the tool-free bite point and reach adjustments from the Tech 3. All Tech 4 brakes are supplied with new racing compound pads. Two huge 25mm aluminium pistons offer great power and stiffness.Buy Hope Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Fulcrum Red Zone 3 WheelsetEngineered for dependable performance wherever your mountain bike (MTB) takes you, this versatile wheelset is perfect for all-day epics on the trails and exploring new mountain routes. Fulcrum has kitted out this model with durable aluminium rims that have been put through the brand's square milling and CNC-machining process to deliver maximum strength without adding any unnecessary weight. This results in a more capable wheelset that can handle the intensity that's associated with charging across demanding terrain conditions at speed, across rock gardens, tree roots and debris.Aluminium MTB WheelsetFulcrum's second MTB wheel is the result of the experience matured in the development of the Red Zone Carbon. It's designed for a wider range of riders looking for a reliable and resistant product for off-road fun and performance.Amongst the technical specifications derived directly from its older sibling we find the hubs and the spoke count of 24 on the front and 28 on the rear. The CNC machined aluminium rim has a profile of 19mm and an inner rim width of 25mm. Aesthetically the wheel is completed with an advanced finish that marries a double polished-matt surface with laser-etched graphics. The Fulcrum logo can be found inside a red box, which can also be replaced with a reflective adhesive, black on black, included with the wheels.The Red Zone 3 is an all-purpose wheel, which is extremely versatile and suited to multiple uses: training wheels, sturdy race wheels or the perfect base for adventure bikes (boost gravel).Boost Axle SpacingBuilt for modern MTB trail riding, the Fulcrum Red Zone 3 Wheelset is equipped with Boost axle spacing for stiffer and stronger rolling performance across harsh and unpredictable terrain conditions. Its 15x110mm front spacing and 12x148mm rear spacing gives it extra stability as you carve your way from trail to trail.Features: Rim Material: Aluminium with Square Milling, CNC-machined Use: Mountain Bike (MTB) Rim Width: Inner: 25mm; Outer: 29mm Rim Height: 19mm Asymmetric Profile Height: Low Axle Size: Front: 15x110mm (Boost); Rear: 12x148mm (Boost) Brake Type: Disc Brake Tubeless Ready: Yes 2-Way Fit Ready: Yes ASTM Category: 3 Braking Surface: AFS Front Wheel Spokes: 24 Rear Wheel Spokes: 28 Spokes Material: Stainless Steel - Double Butted Spokes Profile: Rounded, straight pull Nipples: Aluminium Front Hub: Aluminium Flanges Rear Hub: Aluminium Flanges Freehub: Multiple options available to select Bearings: Adjustable Cup and Cones bearing Others: Optional Reflective "F" sticker Weight Limit (System): 125kg ASTM Category: 3 Single or Pair: Pair Weight: 1610g Technologies: Wide Rim Tech: Fulcrum's Research and Development department, following requests from the competition circuit, has worked to create rims that are wider than before, about 4 mm or more than previously. This technical choice provides an ideal basis for 25/28mm tyres, the sizes currently popular. This ensures stability, excellent handling and superior comfort. Cup and Cone: The cup-and-cone bearing differs from the classic cartridge bearing because it works in perfect alignment with the forces involved, weight and thrust from the frame, as the bearings run in a race positioned directly opposing these forces. Square Milling: For the new Racing Zero's aluminium rim, Fulcrum decided to keep the triple-milled structure throughout the profile to minimise aluminium thicknesses. Next, Fulcrum's technicians added 3D milling at the base of the spokes. This means less material but the same reliability since, in this particular design, the forces are well distributed over the rim. Triple and “Square” milling enable maximum weight reduction on the rim periphery, producing an extremely responsive wheel. Asymmetric Rim: The asymmetry is designed to improve rim tension, balancing the forces from brakes and sprocket cassette.
