Castelli Emergency Rain JacketFrom intermittent showers to more prolonged bouts of rain, when you're on the bike, the Castelli Emergency Rain Jacket ensures you always have compact wet-weather protection to hand.Castelli have kept it simple with their Emergency Rain Jacket. They've chosen to make it from Deluge Light 2.5-layer waterproof fabric. This gives a waterproof rating of 10,000 mm, and in combination with a waterproof zipper and sealed seams locks out the rain. You'll also find a longer tail to keep tyre spray off and the long sleeves with wrist closures fit easily over gloves. The only real compromise is it's not quite as breathable as more expensive jackets in the Castelli line.With a slight stretch in the fabric, the jacket has a snug fit that reduces the annoyance of flapping. But it's got enough space so it's fine to fit over a winter jacket too. If the rain passes then it folds up into an integrated stuff pocket, making it easy to pop in a jersey pocket. Features:Materials: 100% PolyamideDeluge Light 2.5-layer waterproof fabric keeps rain off with 10,000 mm water columnSlight amount of stretch for excellent fit in riding positionFolds into half a jersey pocket for emergency situationsStuff pocket integrated into mesh vent at top of backWaterproof zipper and contrast seam sealing keep water out360-degree° reflectivityWeight: 149g (M)Suggested temperature range: 6 to 18 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.

SRAM XG-1270 12 Speed Road CassetteEngineered for the next generation of road bike drivetrains as well as the next generation of riders, this road bike cassette is equipped with some of SRAM's finest technologies for reliable performance on every ride. It's optimised for electronic shifting and its X-Range gearing gives you more range and a smoother gear progression, so you’re always in the right gear. Coming equipped with a Mini Cluster construction that reduces weight and increases durability, this model is a great choice of upgrade for smooth, precise shifting from 10T and up.Features: Material: Steel Finish: Nickel-Chrome Use: Road Speed: 12 speed Driver Body Interface: XDR Cassette Technology: HG Cog Sizes: 10-28T Option: 10,11,12,13,14,15,16,17,19,21,24,28 10-33T Option: 10,11,12,13,14,15,17,19,21,24,28,33 10-36T Option: 10,11,12,13,15,17,19,21,24,28,32,36 Technologies: Mini Cluster: The Mini Cluster hybrid cassette construction combines four small cogs that are CNC-machined out of a single block of billet steel with an additional eight cogs that are individually pinned together. The result: a cassette that’s light, durable and equipped with a gear range that’s a perfect fit for any ride. XDR: The XDR driver body is a universal mounting system for cassettes that incorporate cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring new rear axle standards, cassette tools or hub redesigns. The XDR interface is 1.85mm longer than XD and is designed for road hub applications. XDR driver bodies are compatible with all XD cassettes when the cassette is installed with a 1.85mm spacer. All Zipp wheels starting from 2015 are XDR ready. X-Range: Road bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range is gearing for today’s road riding. We completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings—enabled by AXS. With X-Range, you’re always in the right gear.
