    Description

    Cyclocross is growing fast. Drawn by the fun of the mud and the thrill of the racing, cyclists are taking to the 'cross course in droves. CX is a balance of speed and skill and the Planet X XLS R8000 is an eternal favourite of the scene, thanks to its contemporary and refined carbon chassis and race-tuned geometry. Whether you're looking to upgrade to carbon or discs, the XLS is the perfect place to start.

    The XLS represents the evolution of technology within cyclocross, namely, the introduction of disc brakes. If you're a road rider that's never experienced disc stopping power, you'll be thrilled with their performance. No longer must you compromise on speed - on discs you can brake later into corners and shred mud like never before, as the discs stay clean. This performance increase is even more outstanding when coupled with the XLS' lightweight carbon frame and fork. We've cleverly flattened the top-tube for comfy 'shouldering' over the roughest off-road terrain, too. There's big tyre clearance too, to avoid mud clogging. With features like these, we've made sure the XLS is future-proof.

    The XLS frame is beefed-up around the main frame joints for extra strength so it can easily handle the rough stuff. In fact, the XLS wants to be ridden hard, to show off how efficiently it transfers every watt of pedal-power into speed. Go on, drop the hammer, search for the limit, gap the field.

    Of course, with a bike this tough, theres the added advantage of using it for multiple types of riding. Wash off the race mud and enjoy its versatility as a commuter or road bike. Put some slick-tyres in there for the weekend club run. The XLS is quickly gaining popularity for good reason!

    Groupset: Shimano's Ultegra groupset has been upgraded and the result is the incredible Ultegra 8000 groupset. Shimano have worked to improved the efficiency of the shifting, improved brake feel and delivers a smoother working, better-looking groupset that's simply worth every penny. With a larger downshift paddle and lever adjustable cable tension they've eliminated inline cable adjusters forever.

    A compact FSA Gossamer Pro 50/34t chainset combines with a 11/34t 11-speed cassette to give an excellent gear spread, close enough for road work but still including a bailout gear for tackling those ultra steep climbs CX climbs. The new Shimano RX800 rear mech features a quiet clutch mechanism that improves chain retention and delivers improved shifting performance.

    If you've ridden Ultegra before you know how much care and attention Shimano put into it. It's their best selling groupset and offers the best mix of price/performance. This new version is no exception it's simply superb.

    Avid's BB5 mechanical disk brakes provide huge amounts of stopping power and great feedback through the brake levers. They're a cinch to set-up and require next to no maintenance making them perfect for a serious season of CX racing.

    Wheelset: Gipiemme Rocky's Disk Built for road and off-road use this hand built version of the Gipemme Roccia is supremely versatile, perfect for our commuting , Gravel and cyclocross builds. Disc brake ready and built to last the Roccia is a great do it all 700c / 29er wheelset. We've made this wheelset even better by hand building them, better than a machine built wheel these will roll and roll.

    Upgrades:If you're in it to win it we have some amazing wheel upgrade offers to help you take your riding and racing to the next level. We've lightweight alloy wheel upgrades from Fulcrum that'll help you shed grams and improve your lap times. If you're really serious about your cycling then upgrade to Vision's Metron 40 disc brake ready carbon clincher wheels. With a 40mm deep aero section and ultra lightweight construction the Metron 40's are incredbly strong, quick to accelerate and best of all, they're suitable for clincher tyres so you're sure to be able to run your favourite rubber. And of course they're all available at a significant saving over typical retaill prices.

    Please Note: All customizable options are fitted in house during the build process by our trained mechanics.
