Castelli Perfetto ROS 2 Long Sleeve JacketWith superb windproof protection, water-repellency for light rain and outstanding breathability, the Castelli Perfetto ROS 2 Long Sleeve Jacket could be just the one cycling jacket you need this winter season. Rain or ShineThe Perfetto ROS 2 Long Sleeve Jacket is part of the super-versatile Rain or Shine family of garments. When it's cold and wet, the Castelli-exclusive GORE-TEX INFINIUM™ WINDSTOPPER® fabrics keep you dry. And in drier and milder conditions, outstanding breathability keeps you comfortable too. Gore-Tex INFINIUM™ WINDSTOPPER®To the front of the jacket, water-resistant INFINIUM™ WINDSTOPPER® material, with a light fleece inner face, keeps out both wind and rain. Across the back a lighter and stretchy version of INFINIUM™ prioritises breathability. Because these fabrics don't require a membrane, they ensure you're not drenched in sweat after higher tempo efforts. Because you're drier there's less need for multiple layers underneath. Simply pick your base layer to suit the weather - lightweight when it's mild, heavier weight when it's freezing cold. If you do find yourself feeling a touch too warm, zipped chest vents allow you to dump heat and introduce some extra airflow.Perfetto. Part 2.The ‘2’ in the title signifies several key improvements compared to its predecessor. You now have the convenience of a two-way YKK® Vislon® zipper to the front, making it easy to ventilate from the bottom while keeping your chest covered. Reflective details have also been made more visible.Seams at the top of the shoulder have been repositioned to the back out of the way of the weather. Pockets have also been made larger to hold more gear. While the fit remained focused on smooth performance, there’s now a bit more space across the chest, shoulders and biceps.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 protectionZippered ventilation opening on side of chest3 rear pocketsReflective panel at bottom of pocketsWeight: 296gSuggested Temperature range: 4 to 14 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
Shimano GRX’s mid-priced RX600 cranks employ a 2-piece design and are available in 2x11 and 1x11 configurations. All GRX cranksets use a new, +2.5mm chainline for increased tire and frame clearance. The 2x features a Wider-range 46-30T ratio, this, when paired with the available 11-34 cassette, offers an exceptionally low climbing gear while maintaining a ratio that allows riders to take advantage of strong tailwinds and long descents.RX600 series cranks also are available in a 40T single chainring option for those who prefer the simplicity and decreased weight of a 1x11 drivetrain with one of Shimano’s wide ratio 11-40 or 11-42T cassettes.Choice. Shimano’s new GRX line is all about choice. Shimano doesn’t want to pigeonhole the way you ride, or decide for you what the best solution is for your riding style. While we’ve long been fans of double chainring drivetrains, we also recognize the value of a single chainring system. With GRX, Shimano offers both, each with gearing options that allow you to tailor your drivetrain to suit your tastes.With two different derailleur cage lengths, Shimano GRX ensures stable shifting and chain retention across a wide range of gearing options. Looking for maximum range while maintaining road cassette progression? Go with GRX’s 800 series 2x11 RD-RX810 or Di2 RD- RX815 rear derailleurs, designed for close ratio clusters, with 48/31 chainrings and an 11-34 cassette. Paired with 700c x 40mm tires, it delivers a top gear similar to a road bike with 25mm tires and a 50 x 11 gear. And on the low end, with its 31 x 34 combination, you get a gear that early mountain bikers would envy. It is the lowest gear currently on offer for premium road drivetrains (aside from Shimano’s own GRX 2x10 30-36 offering), perfect for climbing loose, dirt and gravel surfaces.Want to drop some weight, simplify your shifting, and still maintain a versatile range? Consider the 1x11 GRX option with either Shimano’s 11-40 or 11-42 cassette and a 40 or 42-tooth equipped crankset, shifted by a RD-RX812 or Di2 RD-RX817 wide ratio rear derailleur. You’ll lose a little, absolute top speed, but still love the 1:1 low gear ratio. If you live in an area without sustained or steep climbs, you might love the smaller gear steps of that same 1x11 front chainring with an 11-34 cassette. Options abound.What about when the weather turns autumnal and you contract a case of cyclocross fever? GRX 1x11 can quickly transform from gravel fun to CX focused with the change of a cassette.No matter the option you select, GRX rear derailleur offerings feature Shimano’s SHADOW Plus chain stabilizer that can be turned on or off depending on conditions. SHADOW Plus revolutionized the mountain bike world and now it’s been tuned for gravel and rough road riding in GRX. With a quieter drivetrain, SHADOW Plus helps you engage with your surroundings and enjoy time outside.Today’s gravel riders demand more of their bikes and of themselves. Shimano GRX gives them the options they need to Explore Beyond, tailoring their drivetrains to suit their needs and exceed their expectations.

Fizik Terra Argo X3 K:ium Rail Gravel SaddleEnsuring maximum durability and strength without adding any excess grams to your ride, this Terra series gravel bike saddle is kitted out with a high-quality carbon reinforced nylon shell to take you beyond your boundaries. Fizik has also equipped this model with Wingflex technology at the edges of its shell, so riders can benefit from supportive flexibility that adapts to their inner leg movement. This controlled elasticity absorbs road chatter and vibrations, delivering the comfort needed for long-distance riding over mixed terrains and unpaved roads. With the addition of hollow K:ium rails that use a Mobius closed-loop design, this saddle provides extra strength and weight distribution, making it a reliable and stable choice of upgrade for wherever your next gravel adventure leads you.Greater StabilityWhere a traditional saddle shape encourages riders to shift their position frequently for better leverage, the Argo puts riders in a more planted position, making for greater stability and better weight distribution. The Terra Argo's short length allows riders to sit further forward without placing undue pressure on sensitive areas. It also features an ergonomic cut-out that was developed using detailed pressure analysis and input from medical experts.Stability and ResponsivenessTo better support the Terra Argo's flexible shell, Fizik used its closed-loop Mobius rail system for increased structural stability and responsiveness. The Terra Argo features a waved profile to provide the lower-back support necessary for long rides and to help riders hold their position while climbing on loose terrain. The same goes for the dropped-nose design which allows riders to rotate their pelvis while pushing forward on the nose for better traction and power transfer.Long Distance ComfortThe padding is made from Fizik's proprietary Type-2 foam formulation, slightly thicker around the ischial sit bones area to support a more upright riding posture. The cushioning is slightly softer and more progressive than the type used on the brand's racing saddles, providing more long-distance comfort.Features: Shell Material: Carbon Reinforced Nylon Rails Material: Hollow K:ium Mobius Padding Material: Type 2 Foam Use: Gravel Dimensions: 150mm Option: 150x270mm; 160mm Option: 160x270mm Rails Size: 7x7mm Height at 75mm Width: 47mm Length from Nose to 75mm Width: 113mm Weight: 150mm Option: 238g; 160mm Option: 245gTechnologies: Argo: Versatile short-nose saddle that encourages stability and relieves pressure on sensitive areas. X3: A combination of a ride-compliant, carbon reinforced nylon shell and a Kium hollow rail with a high strength-to-weight ratio. Mobius Rail: Closed-loop design for added strength and weight distribution. Wingflex: The shell's side edges flex and adapt to a rider's inner leg movement. Type 2 Foam: Progressive cushioning, with a lower compression modulus. Terra: All-terrain series designed to take you beyond your boundaries. Concepts: This is a product of the Fizik Concepts programme, a cross-disciplinary collaboration of leading industry experts and academics carrying out research and analysis on technology, design, physiology and bike-fitting in search of ways to improve cycling performance.Manufacturer's Part Numbers: 70E1SA03A22 Black 150mm 70E2SA03A22 Black 160mmBuy Fizik Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
