◌Giro Imperial Road ShoesProfessional performance meets all-day comfort and unrivalled ventilation, placing the Giro Imperial Road Shoes on the top step of the podium when racing and training. Lightweight shoes are all very well but they can often lack the support needed for a stable pedalling platform, leading to loss of efficiency. Giro has tackled this by combining their highly innovative One-piece Synchwire upper with the impressively stiff Easton EC90 SLX2 high-modulus carbon sole unit, providing a supportive shoe with optimal power transfer and remarkably low weight.Synchwire UpperThe proprietary Synchwire upper construction is what provides the foot support and stability needed for efficient pedalling. A combination of an ultralight monofilament mesh, reinforced with thermal-welded Teijin TPU lets Giro strip out the weight, boost ventilation and yet still maintain durability where you need it and a supportive hold across the whole foot. This design hits the sweet spot between low weight, support for fluid pedalling and a high degree of breathability for those hot days on the bike when even the tarmac begins to melt. Precision BOA IP1 AdjustmentA secure and comfortable fit is achieved via the double BOA IP1 dials. On the fly adjustment is incredibly quick and easy, a twist of the dial offering up 1mm of micro-adjustment per click. With the Boa chord running in reinforced webbing runners you'll enjoy a smooth closure and a snug fit that eliminates hot spots and pinch points.EC90 SLX2 High-Modulus Carbon SoleThen comes the heart of any performance cycling shoe - the outsole. Here you'll find Giro's high-modulus Easton EC90 SLX2, delivering perfect stiffness-to-weight so you enjoy optimal power transfer to the pedals and minimal flex. While it's not the lightest sole unit Giro make it has the durability to stand up to your daily training and hard riding weekend races. Inside the shoe, the adjustable Super Natural Fit footbed system provides optimal pedalling efficiency with customizable arch support for performance and luxurious comfortThe result of this blend of light and airy upper, Boa fit system and stiff but durable carbon sole is a race-ready shoe which provides the perfect pedalling platform for smooth power transfer and maximum pedalling efficiency. From one hour criterium to your very own Grand Tour ride the Imperial is the ultimate choice for best in class comfort and performance.

Look keo blade carbon ceramic bearing ti axle with keo cleat 16nm with 12nm spare.Blade carbon pedalOur elite-level, top-of-the-range weapon designed for pure racing performance. The unique, patented blade technology is combined with the unequaled properties of ceramic bearings and look’s signature power-to-weight ratio, ensuring the pedal comes straight in as a reference on the market.CeramicFaster - longerEvery component, every ball is meticulously selected to ensure the highest level of quality and performance. The balls are precisely calibrated one by one by a machine, down to the micrometer. They are then ordered according to size in perfectly-adapted rings, with the result that every bearing has a totally unique structure.Longer lifeA long lifespan is the main advantage of ceramic bearings. Rounder and harder than traditional balls, they are less sensitive to dust or deposits and guarantee consistent, durable performance. Furthermore, ceramic is not subject to corrosion. These physical properties ensure the bearings have a lifespan 4 to 6 times longer than standard steel bearings.SmootherReduced friction is the best-known and most characteristic advantage of ceramic bearings. The perfectly circular shape and the hardness of the balls combined with ceramic-specific, optimized greases allows for an 18% reduction of the frictional forces applied to the bearing.SpindleIn order to meet the requirements of the most demanding cyclists, the blade carbon pedals are designed to resist the very worst weather conditions. Particular care is given to each component within the axle to ensure optimal lifespan. The axle is guaranteed waterproof by ipx7 (full immersion) and ipx6 (rotating pedal exposed to water jets) tests. The design of the outer cap and the inside nut have been revised to meet these requirementsBlade technologyLighter – aerodynamic - saferThe use of a carbon blade instead of a conventional metal spring offers numerous advantages:The “blade – lever” system is 20% lighter than a standard “spring – lever” system.The carbon blade blends fluidly into the shape and volume of the pedal, improving the overall aerodynamic properties of the product.The blade technology revolutionizes the engagement/ disengagement experience whilst offering firm and secure support. The bowing of the blade when unclipping means the required disengagement torque is reached more rapidly in the dynamic of the movement, allowing for faster cleat release. Pedaling experience is also improved thanks to a firmer lateral stop.The carbon blade is available in various stiffness options: 12, 16 or 20. The blade can be easily, intuitively and quickly (a few seconds suffice) changed depending on the rider’s clip-in / clip-out preferences.Technology: blade,Retention: serial installed in 16 + additional 12 in box 20 sold separately,Body: carbon,Traction: carbon,Spindle: titanium,Bearings: ceramic,Platform area: 700 mm²,Platform width: 67mm,Q factor: 53mm,Stack height + cleats: 14,8 mm ( 8,5 + 6,3 mm ),Weight (pedal): 95g,Weight pair + cleats: 260g,.
Troy Lee Designs D4 Composite HelmetA classic of the mountain bike world, the Troy Lee Designs D4 Composite Helmet has a well-won reputation for delivering superb levels of comfort, protection and distinctive style. Pull it on and go get your mountain bike thrills in style. No matter where you get your mountain bike thrills, from weekend races on challenging downhills through to racing buddies to the bottom at the local trail centre or bike park, the D4 Composite Cycle Helmet has you covered. Confidence is given a boost thanks to its superb combination of safety features, unrivalled comfort and the usual Troy lee flair for design. Keeping weight low but protection and durability high is the aerospace-grade fibreglass composite shell. This wraps around an impact-absorbing EPS foam core - the forces from any crash are absorbed and dissipated by this core, offering outstanding crash protection. Meanwhile, breakaway screws prevent the visor from catching on the ground and help prevent neck injuries. Lastly, MIPS (Multi-directional Impact Protection System) provides excellent brain-injury prevention - more on that below.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. In a crash, the Mips system is designed to move slightly inside the helmet to help redirect forces away from the head.Uncompromised ComfortWith this level of protection and head protection, you may think ventilation is compromised. But not a bit of it. Troy Lee have carefully engineered the outer vents and inner channels to work with the headliner so fresh air is free to circulate and keep you cool.Inside the D4 you'll also enjoy the brilliant XT2 washable liner. 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.Tough, durable, protective and yet lightweight, the D4 Composite is the ideal full-face helmet for the weekend DH racer and avid mountain bike trail slayer.Features:Aerospace shell design and materials (D4 Composite)MIPS C2 brain protection systemFront air intake system with high flow through polymer centre and powergrid side meshCollarbone suspension systemBreakaway visor screwsX-static® and XT2® Anti-Microbial/anti-order paddingQuick-release contoured 3D cheek pads create an anatomically optimized fitWeight - 1050gCPSC 1203*, CE EN1078*, ASTM F1952 - DH, ASTM 2032 - BMX, *Varies by regional standardsShop all MIPS helmets - Click hereBuy Troy Lee Designs from Chain Reaction Cycles, the World's Largest Online Bike Store.
