The result is less control in the corners, less traction on climbs, and more rolling resistance. Rims that are too wide also distort the tyre profile, decreasing traction and control and driving impacts directly into the rim, negating the impact absorbing advantages of a tyre's volume. Stan's WideRight rim widths are designed to strike the perfect balance between tyre volume and sidewall function. BST (Bead Socket Technology): Bead Socket Technology rims are designed to match the shape of your tyre's bead to create a safer and more secure airtight interface. BST rims secure the bead of the tyre, not the sidewall, creating an airtight seal while allowing the tyre's sidewall to expand to its true, rounder, more effective profile. The result is more traction and less rolling resistance. With lower-profile, less vulnerable sidewalls, Stan's BST rims are also lighter and stronger by design and accelerate more quickly. Neo Hub: The Stan's Neo hub has a 100% precision CNC machined hub shell that is both incredibly light and strong. It features a 4 pawl, 36-point drive system for amazingly quick engagement. Oversized bearings ensure maximum durability and the swaged axle & wide bearing stance is 3 times stronger than conventional designs. There is a high durometer main seal integrated into the hub shell and the Sealock end caps lock into place bringing unmatched smoothness.Buy Stan's No Tubes Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.

Troy Lee Designs D4 Carbon Stealth HelmetTroy Lee Designs have yet again pushed the boundaries of mountain bike protection with their superb D4 Carbon Stealth Helmet. Sleek TLD style, outstanding comfort and the inclusion of the very latest impact-absorbing technologies create a helmet with unrivalled performance on the trail. If you're charging downhill, ripping up gnarly trails and going big off the biggest booters then things won't always go smoothly or to plan. For those times when you hit the ground after casing the landing, push grip too far or get your line wrong the D4 Carbon Stealth Helmet ensures you can get up, dust yourself off and keep riding. Carbon ShellIt starts with the TeXtreme® Spread tow carbon fibre shell, giving the D4 incredible strength while keeping weight to the minimum. This shell covers the EPS foam shock-absorbing core - if you hit your head it's this core that will absorb the forces and protect your head from the impact. To boost strength and durability Troy Lee also uses In-mould polycarbonate around vent openings and exposed EPS, making this a lid you can use day after day without fear. Lastly, MIPS (Multi-directional Impact Protection System) provides excellent brain-injury prevention - more on that below.AirflowVentilation is also fabulously realised. The outer vents bring in fresh, cooling air and this is allowed to circulate easily thanks to carefully designed channels and integration with the headliner. It's like a turbo-charger for your head.XT2 ComfortSpeaking of the liner, this is the XT2 washable design. Lesser helmets will use standard foam liners which after continued use can soon start to feel uncomfortable and even itchy. Not the XT2. This anti-bacterial liner ensures no nasty odours or itchiness, and being washable you'll be able to keep it fresh for every ride. Fresh, lightweight and cool mountain biking is now here for you to enjoy, even in a fully-featured full-face helmet.MIPS (Multi-directional Impact Protection System) The Mips system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head.Rotational motion is a common cause of concussions in oblique hits to the head.

This is an updated version of the Oversized Pulley Wheel System for Shimano 9100/9150 and 8000 SS/8050 SS. This new design has an integrated stop tower for easier mounting. The CeramicSpeed Oversized Pulley Wheels System has been proven to be the fastest pulley system in the world, providing energy savings starting from 2.4 watts over standard Shimano systems. The OSPW System for Shimano 9100/9150 and 8000 SS/8050 SS is an industry-leading product, chosen by many of the world's leading cycling teams and professional triathletes. Featuring a 13-tooth upper pulley wheel and a 19-tooth lower pulley wheel to provide absolute optimisation of the rear derailleur. The upper and lower oversized aluminium pulley wheels come fitted with either standard or coated CeramicSpeed Bearings. Please note: The OSPW System for 9100/9150 and 8000 SS/8050 SS is NOT compatible with Ultegra 8000-GS or 8050-GS (medium cage) derailleurs, nor with the clutch equipped Ultegra RD RX800 and RX805. Also note: while there are design similarities this OSPW is not compatible with the 12-speed Shimano 9200 or 8100 series derailleurs. The Shimano 9100/8000 OSPW system is compatible with up to a 32 tooth cassette for both Dura-Ace and Ultegra derailleurs Everything from bearings to the cage is made from the highest quality materials. The oversized aluminium pulley wheels are fitted with standard or coated CeramicSpeed Bearings, which reduce friction to the minimum. The overall power savings of the OSPW System for Shimano reach 30%-60% or more in some cases. The OSPW System has a lifetime that lasts 3-5 times longer than the commonly used standard pulleys on the market. The OSPW System for Shimano comes as two different systems, one compatible with Ultegra (6700/6770/6800/6870) and Dura-Ace (7900/7970/9000/9070), 10s and 11s, electric and mechanical groupsets, and another compatible with the Shimano 9100/9150 series. While the first option features a set of two 17-tooth pulleys, the OSPW System for Shimano 9100/9150 features an optimal 13/19-tooth combination specially developed to fit the design of the derailleur. IMPORTANT: When travelling, please remember to dismount your entire rear derailleur with an Allen key, as the OSPW System will not fit in most bike travel bags and could be damaged if left on. The revolutionary OSPW System is developed, produced and assembled by hand in Denmark. The product is the result of an in-depth development process and has been designed for optimal performance. Like all other products delivered by CeramicSpeed, OSPW System has also undergone a thorough test program. We are proud to say that professional triathletes such as Tim Don and Tyler Butterfield have great feedback for the system and, along with Pro Continental teams, they have made it a permanent part of their equipment. Regarding the maintenance of your OSPW System, it is important that you properly lubricate your bearings in order to ensure optimal performance and maximum longevity. Add oil by using the lubrication points on the back cage plate, so that oil can penetrate the bearing. Do this when you lubricate your chain, if you have washed your bike or after riding in wet or muddy conditions.
