Castelli Women's Gabba ROS 2Come rain or shine, the 5th generation Castelli Women's Gabba ROS 2 won't let you down. With improved water resistance it's now even better in the rain but it still retains the brilliant breathability and windproof protection you'll love, making it great for all weather eventualities. The Gabba made its revolutionary debut back in 2010. And ever since then it's been the benchmark by which all-around cycling performance is judged. The Women's Gabba ROS 2 excels in the cold and wet, keeping you warmer and drier. But in dry and milder conditions, excellent breathability ensures brilliant comfort too. The incredible versatility has been achieved thanks to the use of two Castelli exclusive Gore-Tex INFINIUM™ WINDSTOPPER® fabrics. Gore-tex INFINIUM™ WINDSTOPPER® 205 is deployed across the front, sleeves and shoulders. This faces into the weather and offers complete wind protection, a high degree of water resistance and a brushed inner face to hold in warmth. Across the back of the jersey, meanwhile, lighter and high-stretch INFINIUM™ WINDSTOPPER® 203 gives a snug fit and outstanding breathability. When there's an injection of pace or a rise in temperatures, this ensures you don't overheat and get a chill from cold sweat. It’s water-repellent too, fending off road spray.Compared to the previous iteration the Women's Gabba ROS 2 gets some key detail improvements. In order to improve control of ventilation, the KK® Vislon® front zipper is now two-way. This lets you introduce airflow to either the top or bottom of your body. For low-light cycling, the reflectivity is now more visible and pockets to the back now hold more gear. Lastly, seams at the shoulders have been moved to the back, reducing exposure to wind and rain. The Gabba RoS 2 is a must-have for autumn and spring riding when weather conditions can change in an instant.Features:Materials: 100% PolyesterCastelli-exclusive GORE-TEX INFINIUM™ WINDSTOPPER® 205 Warm brushed water-resistant fabric on front-facing surfacesGORE-TEX INFINIUM™ WINDSTOPPER® 203 Stretch on rear-facing surfaces for greater stretch and breathabilityTaped shoulder seams for extra rain protectionTop- and bottom-opening YKK® Vislon® zipper for easy sliding, covered for additional wind and rain protection3 rear pocketsReflective panel at bottom of pocketsWeight: 215gSuggested Temperature range: 9 to 16 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.

Giro Helios Spherical Road Helmet (MIPS)Created for cyclists who seek the ultimate in performance-focused safety, the Giro Helios Spherical Road Helmet (MIPS) is packed with cutting-edge features to make your ride comfortable and provide effective crash protection.Whether you're mixing it up in a local race series, putting in some training miles or out to simply enjoy the thrill of riding fast, should you be unfortunate to crash, the Helios Spherical Road Helmet (MIPS) is designed to offer a high level of head protection. We hope you don't have to test its abilities but thanks to advanced construction and MIPS® Spherical Technology it's got you covered should you fall. MIPS® Spherical TechnologyThe 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.Comfort is a BreezeWhen you're working hard on the bike, generating big watts and picking up the pace, sweat and heat build-up is inevitable. However, with 15 Wind Tunnel™ vents, the Helios offers a rush of cooling air over the scalp. Air is forced through internal channels to optimise the cooling effect and exhaust vents let damp, warm air out. The rush of speed is matched by the rush of ventilation.You'll also have the sweat-absorbing performance of Ionic+ padding. This anti-microbial padding prevents the sting of sweat from running into the eyes and stops an itchy scalp after a sweat ride. Roc Loc® 5 Fit SystemInside the Helios is the light and airy Roc-Loc® 5 Air fit system. This is the industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing fit and comfort, Roc Loc® 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand.
