Fizik Tempo Decos Carbon Wide Fit Road ShoesLightweight and breathable, and with a full carbon sole for efficient pedalling, the Fizik Tempo Decos Carbon Wide Fit Road Shoes are engineered for the demands of epic summer rides. A wider fit makes more space for improved comfort for wider feet. Fizik's ethos is to take a minimalist approach to design, giving you pure cycling performance without distractions. And this is certainly the case with the Tempo Decos Carbon Road Shoes. From the challenges of epic rides in mountainous terrain to the speed and thrills of races, they prioritise all-day comfort and incredible power transfer to your pedals. Wider in fit than the standard Tempo Decos, you'll find there is more room across the fore-foot, higher volume over the ball of the foot and wider metatarsal space. All this leads to greater comfort for the cyclist with a need for a wider fitting shoe.Minimalist Design. Maximum Comfort. With its smooth, supple and highly ventilated upper, the Tempo Decos Carbon Road Shoes strike a harmonious balance of comfort, breathability and low weight. The smooth upper also reduces seams, preventing chafing and giving the shoes their distinctive style. During the heat of summer, the copious vent holes also ensure you enjoy fresh feet as the kilometres fly by. BOA® Li2 Fit SystemTo give a precise and comfortable fit, the Tempo Deco uses a single Li2 BOA dial. Composite over-mould on the dial allows improved grip and input toque, making it easier than ever to tighten and loosen your shoes. With quick and easy micro-adjustment, fine-tuning the fit to your particular foot shape is now incredibly easy. The Li2 dial also has a lower profile than previous versions, marginally improving aerodynamics while also making them less vulnerable to being accidentally hit.UD Carbon OutsoleAchieving a 10 out of 10 on Fizik's stiffness scale, the UD carbon composite sole unit will ensure you surge ahead of the pack with maximum efficiency and ruthless accelerations. With your power going straight to the pedals all your hard training to get race fit isn't wasted.Fizik have also prioritised great ventilation. Airflow is channelled inside via a smooth intake vent and allowed to circulate, keeping your feet cool and fresh during the heat of long summer rides and the intensity of hard training and racing. Cleat GuidanceThese Road Shoes are compatible with road bike pedal systems that use cleats with 3-bolt standards, such as: Look Delta and Keo, Shimano SPD-SL, Speedplay Light Action, Zero, X-Series (via 3-hole adapter plate), Campagnolo Pro-Fit, Mavic Zxellium, Time Iclic/Xpresso and Time Impact.Features:Lightweight ventilated upperWide fit - more fore-foot volume and wider space across metatarsalsUD Carbon Outsole - Rated 10/10 on the Fizik stiffness scaleSole vents for improved airflowRecessed cleats positioningBOA® Li2 single-dial Fit System and FizikBi-Directional adjustment with composite over-mould for better grip and higher input torque3-bolt cleat compatible (cleats not supplied)Buy Fizik Footwear from Chain Reaction Cycles, the World's Largest Online Bike Store.
Fizik Gravita Versor Clip MTB ShoesEngineered for the thrills and spills of fast riding, heart-pumping, adrenalin rushing mountain biking, the Gravita Versor Clip MTB Shoes offer comfort, support, durability and pedalling efficiency. What more could you want?The Gravita Versor Clip MTB Shoes form part of Fizik's Gravita range, focused on the fun of gravity-fed mountain biking. They'll deliver the goods on fast trail days and lift-assisted big-mountain downhill runs. A versatile shoe for all your MTB escapades. X6 Outsole. Clip in and Stay in Control.The heart of the Versor Clip shoe is the X6 Outsole. It's this that keeps you confidently on the pedals and is crucial for reacting quickly, aggressively and nimbly to changing terrain and trail features.For the clipped version of the Gravita Versor, Fizik has utilised a Vibram tread compound. This isn't quite as sticky as that found on the flat-pedal shoe but makes for a smoother engagement and disengagement from clip-in pedals.The rubber compound is formed into a zonal lug pattern. Low profile mid-foot tread offers an optimal mechanical interface with pedal bodies, keeping you planted even if you don't immediately find your clip in point. Meanwhile, the heel and toes feature a deeper tread for greater traction when hiking back up the hill.Flex is also tuned for the clip-in rider. The stiffness gets a boost, rated 5 out of 10 on the Fizik stiffness scale, optimising power transfer and improving pedalling efficiency. An extended cleat track also allows you to run cleats further back. This gives a flat-pedal feel as you can drop heels for improved stability and control on descents. Ergonomic and DurableFizik's Versor design provides a supportive and comfortable fit, cradling the foot and working with the ergonomic lace-up closure to give the perfect fit every time you ride. While riding aggressively demands toughness the team at Fizik didn't want to add unnecessary weight or bulk. To this end, they turned to a hardwearing ripstop woven fabric for the upper, providing resistance to tearing and ripping and yet remaining remarkably light. It also offers a snug and supportive fit, rather than the bulky look and sloppy fit of many typical gravity shoes. Elsewhere, a PU-laminated toecap and side reinforcements provide protection from wear and tear and ward off rocks and roots - just what you need when you're foot out and flat out. Cleat GuidanceThese MTB shoes are compatible with MTB pedal systems, which use cleats with SPD standard (2-bolt standard), e.g.: Shimano SPD, Time ATAC, CrankBrothers, CrankBrothers Race, Look MTB, Xtreme MTB, Wellgo MTB, Ritchey MTB.
