Spank 350 Boost Rear WheelThis rear mountain bike wheel is strong, reliable and lightweight. Perfect for the hardest routes on the mountainside, this hard-wearing rear wheel features 12x148mm Boost hub spacing, is tubeless compatible and great for enduro and DH riding. Reliably built for taking on the most exhilarating runs, this rear-wheel comes fitted with a 12x148mm Boost hub which lets you fit plus-sized tyres for the boldest ride possible.Coming tubeless-ready to keep Trail, All Mountain and Enduro riders at their peak, the Spank OOZY 350 Boost Rear Wheel is optimised for rough and ready riding. Constructed using a wide rim profile to take on larger tyres and keeps a strong and sturdy form thanks to 32 straight pull, triple-butted spokes.Made with a variety of technologies to keep you rolling through the harshest conditions, this wheel makes the most of its radial compliant and laterally stiff rims. Plus, its rim features an innovative OohBah inverted wall and a BeadBite Anti-burp rim-hook set-up to maintain the shape and structure of the wheels and air pressure in your tyres.Features: Material: Top-Performance Alloy Use: MTB Inner Width: 30.5mm Outer Width: 35mm Hole Count: 32 Valve: F/V Presta Tubeless: Tubeless equipped (tape and valves included) Technologies: Radial Compliance, Lateral Stiffness, BeadBite, OohBah Inverted Inner Wall Hubs Spacing: 12x148mm BoostCassette Compatibility: Shimano/SRAM 9,10 and 11-Speed mountain bike cassettes (not SRAM XD compatible) Single or Pair: SingleTechnologies: Bead Bite: At an incredible range of pressures, Bead Bite is the solution to keeping your tyres burp free and fixed in place. Bead Bite rim technology enhances tubeless use with tyres of all types and with a greater range of air pressures. Bead Bite rims have 6 rows of tiny ridges that run along the vertical and horizontal faces of the bead seats. These tiny teeth create air seals between the rim and tyre as the bead conforms into them under air pressure. They dramatically increase frictional forces on the tyre bead, reducing the beads' ability to move vertically or horizontally (thus improving tyre stability and reducing burps). The bead literally becomes trapped between the vertical and horizontal ridges, even at very low air pressures. Even in tubed applications, Bead Bite rims tend to allow much lower air pressures with reduced risk of pinch flats. Oohbah: The unique OohBah profile allows Spank to manufacture thinner walled, wider profiled, lighter rims without sacrificing strength or rigidity. Wider rims mean stiffer wheels and more tyre spread, leading to greater traction and improved comfort, and tyre performance. The "wave" shape of the OohBah inner tube adds strength and support to the vertical rim flange walls and prevent buckling. Normal straight or curved tube wells must be much thicker, and by default heavier, to offer the same support.Buy Spank Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Shimano XT M8100 Mountain Bike Disc BrakeThe stunning XT M8100 Mountain Bike Disc Brake from Shimano combination features a two-piston caliper and a rider tunable lever for outstanding stopping power on the trails. Its lever gives you an action-optimised cockpit layout for greater flexibility while its reach adjustment suits any hand size. Its caliper offers quicker piston retraction for superior modulation and control, so you'll benefit from a more efficient braking set-up. This lightweight and easy to install model is ideal for taking your off-road adventures to the next level.Features:Material: Lever: Aluminium anodised; Caliper: Aluminium paintedUse: MTB (mountain bike)Caliper Mount: Post MountLever Length: 2 fingerAdjustment: Tool-less reach adjustmentPiston: 2-pistonPads: G03A Resin without finBrake Fluid: Mineral oilWeight: 284g (approx)Technologies:Servo Wave Action: When you pull a Servowave brake lever, initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control.Reach Adjust: Brake lever is equipped with a reach to adjust mechanism. The distance from the handlebar grip to lever can be adjusted to suit any hand size, type of riding and individual rider preferences.Free Stroke: The distance from the initial lever position to pad contact point can be adjusted to suit any hand size, type of riding and individual rider preferences.Ice Technologies: The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride, has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor and Ice Technologies pad to realise the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight.One Way Bleeding: One Way Bleeding was developed for quick and easy prevention of air in our hydraulic system. We have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.Click HERE to check out the Shimano Brake Reference Guides.A 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Of course, the traditional solution to avoiding the cog unwinding itself from the hub in the reverse direction is a left hand threaded lock-ring, butted up tight against the cog. But, as many riders have found out, this historic system can be relatively volatile.Halo thought... there has to be a better way:A splined hub body (with cogs that slide on) and an independent lock-ring that never has to handle rotational forces from the drive..Halo Fix-G hub:The Halo Fix-G hub features a fixed HG spline, machined as part of the alloy main hub body*, with a conventional internal thread for a standard HG type lock-ring (with easy tool fittings). Options available for the left hand side include conventional fixed or freewheel threads..*Note: Must ONLY ever be used with 7mm base 'Wide Foot' cogs such as Gusset 'Double Six' cogs to avoid the cog biting into the alloy splines on the hub. Regular width HG cogs should NEVER be used.Halo Fix-G advantages:Easy and secure fixing & servicing.,Adjustable chain-line.,Twin cog option (can run 2 cogs together.),Accepts from 12T + cogs (for compact gearing).,No need for chain-whip tools..Tech features:Hi-polish custom CNC machined hub shell,,HG type fixed spline.,Japanese sealed bearings.,Hollow M10 Cr-Mo axle.,120mm spacing.,22mm "Large cone-faces" to avoid damage to frame. ,includes cog spacers and alloy lock-ring.,Front Axle Thread 9x1.,Rear Axle Thread 10x1.,Laser logo. 32H, 36H or 48H,HG Fixed/Fixed or HG Fixed/Freewheel types.."The Fix-g hub is great! it runs smoothly as the previous Halo hub but the fact that you can move the sprocket for a perfect chain-line is great and you can feel the difference straight away. Also, it's really easy to do, everyone can do it without a mechanic's help, I think you should advertise this and make it clear for everyone, people don't have to be scared of a new technology"Ivan Fiorilla - 5th Floor riding club - London. The5thfloor.co.ukImportant note regarding threads for fixed sprocket lock-rings:Our hubs must only be used with ISO standard 1.29" x 24TPi L/H fixed cog lock-rings.,Do NOT USE French (1.32" x 24TPi) or Italian (33 x 1mm) standard lock-rings.,The larger diameter French and Italian lock-rings may appear to work but will strip the threads from the ISO hub..Note: General Fixed sprocket check.For correct fixed use, the fixed sprocket should NEVER move on the hub when pedal force is applied in both directions. If the sprocket moves, then something is wrong and continued use with a fixedsprocket that moves will result in damage to the hub..
