Carbon Fibre Rails In addition to the carbon fibre reinforced shell, this saddle has braided carbon rails. These are light, strong and combine with the shell to ensure ultra-efficient power transfer.

The Women's Pro SL Bib Shorts are made from Italian power Lycra® fabric, and this premium material contributes significantly to the outstanding performance of the shorts. Firstly it provides a firm compressive fit across the thighs, along with exceptional flexibility. This provides superb muscle support while still letting you pedal without restriction. It also features coldblack® technology, dramatically reducing heat build-up from direct sunlight and also giving your thighs UPF50 protection. At the ends of the legs, raw-edge leg bands provide a firm and smooth fit. Endura Dropseat™ Ok, let's be honest, going for a natural break can be a hassle when you're using cycling bib shorts. But the unique Endura DropSeat™ System of the Pro SL bib shorts makes it quick and simple. A comfortable and discreet zip-free design makes it incredibly easy to go, all without the need to strip off jerseys and jackets. What a relief. Sleek and Supportive Bib To the upper body, the Pro SLs have a sleek and comfortable full-body design. A high-wicking front mesh panel acts just like a base layer, drawing sweat off the skin for enhanced comfort as the pace picks up. To the back, wide cross-over straps provide comfortable support while lumbar support panels at the side keep the shorts beautifully in place. Women's 800 Series Conform EGM Pad Once on the saddle, comfort is to be found via the innovative Women's 800 Series Conform EGM Pad. This game-changing seat pad uses Medical grade elastomer, as used in prosthetics, to protect key areas from pressure and discomfort. The elastomer, in liquid form, is combined with Endura’s continuous variable profile (CVP) pads creating a seamless interface between elastomer and foam. This combination has proved far more effective in dissipating pressure than traditional foam or gels, creating a seat pad brilliantly protective of the skin and underlying soft tissue.

Redefining Fizik’s identity, the Tempo R5 Overcurve Road Cycling Shoes are perfect for your summer cycling regardless of whether you ride competitively or simply love the thrills. They are quick fitting to get you in the saddle faster and their form-fitting construction works around the foot to offer endless comfort no matter how long your session lasts. When it comes to on-bike performance there are few that can argue with the R5’s reputation. An instant road classic, they sport the famous Overcurve construction that uses a staggered collar to wrap around the ankle. This traces the natural misalignment of the two bony protrusions in the lateral and medial malleoli. Offering riders an asymmetrical shape, the shoe curves over the foot to wrap it like a present and guides all the way from the outside to the inner for one of the cosiest fits yet. Should you wish to adjust your fitting, the closure is assisted by the micro-adjustable BOA IP1 dial that twists to your liking in order to provide customisable comfort. Working in tandem with a Velcro strap to fine-tune your fit, riding in endless comfort and stability ensures you feel as good as the shoes look. The Microtex upper is brilliantly supple and easy to clean plus offers excellent breathability for those scorching days of summer. When the rains come then the sleek style also makes it easy to slip on a waterproof overshoe to keep feet dry. Add in the R5 nylon composite outsole that is capable of delivering explosive power transfers, and in the Tempo Overcurve R5 you have one road shoe capable of opening up a world of endless possibilities. Cleat Guidance These 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.

This disc brake features a robust aluminium construction, which allows it to handle all the abuse that comes with blasting across the mountain at speed. Shimano has also equipped this version with an adjustable lever reach, which means that it perfectly matches your riding style, personal preferences and the terrain conditions. Technologies: Ice Technologies: The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. SHIMANO has adopted ICE TECHNOLOGIES disc brake rotor and ICE TECHNOLOGIES pad to realize the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum 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.

Be it taking your big-hitting bouncy bike on big mountain trails, hardtail XC fun on narrow singletrack or a leisurely family outing on the rough stuff, the Modrop MTB Helmet (MIPS) provides protection in the event of a fall. Head protection comes firstly via the Multi-Shell In-Mould construction. This has a shock-absorbing helmet material permanently bonded to a tough outer shell. The inner EPS foam soaks up and dissipates impact forces while the outer adds structural strength and fends off minor bumps, from overhanging branches for instance. You also have a height-adjustable visor to add protection to your face. In its uppermost adjustment, it also makes space for pulling up and stowing goggles, ideal for moments when you're taking stock, catching your breath, and readying yourself for the next drop-in. 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. Shop All MIPS Helmets Click Here Safe and Secure Excellent safety is also matched with excellent comfort. A good-fitting helmet is essential for both safety and comfort. And here the Zoom Ace MTB adjustment system makes it easy to get the perfect fit. With the rear dial and the built-in height adjustment, you'll be able to get a secure fit every time you ride. And with ponytail compatibility, long hair isn't going to prevent a good fit either. You'll also be pleased to find ventilation is also superb, keeping you cooler when you're building a sweat on your mountain bike trail rides. A total of 14 air vents, 6 to the front and 8 to the side and rear, keep cool air flowing as you pedal. There's also a built-in bug mesh, keeping out those buzzing nasties as you zoom along the trails. Trail features If you love to ride trails with MTB goggles to keep your vision clear, the Modrop features Abus' GoggFit system. This allows you to secure the goggles to your helmet when you're not in need of them. There is also compatibility with QUIN chip system (Chip not supplied) - this works alongside the QUIN app to send an SOS should you crash - keeping you safer on remote trails.
