Specialized Crux Expert X1 Disc Cyclocross Bike 2018
Finished in a truly outrageous colourway that screams to be ridden fast, the Specialized Crux Expert X1 Disc Cyclocross Bike 2018 is the ideal choice for mud-loving, heart rate soaring cyclocross enthusiasts with their eyes on the top step of the podium. Everything from its Rider-First Engineered geometry to a Roval SLX 24 Disc wheelset has been incorporated to ensure you’re riding the fastest and most aggressive cyclocross bike on the course.
The frame and fork are constructed from Specialized’s top of the line FACT 11r carbon fibre, which has been designed to improve your comfort, lower weight and heighten performance when putting down the power on a cold, wet, Sunday morning. It even features Specialized’s renowned Rider-First Engineered geometry, which allows Specialized to bring you the most performance-driven frame on the market. It’s aggressive, snappy and even stable geometry increases your ability to control the front of the race, but also gives confidence in sloppy, muddy conditions.
Of course, all of this technology in the frame means nothing without a capable range of components, and Specialized have truly gone above and beyond with a SRAM Force groupset. The one-by SRAM Force 1, 11-speed drivetrain eliminates any risk of your chain coming off when battling over roots and rocks, whilst its wide set of gears gives more than enough spin to get up those short but steep gradients.
SRAM Force hydraulic disc brakes encourage late breaking into the bends thanks to their highly reliable, powerful braking in every situation, and even the SRAM Force 1 shifters have been ergonomically shaped to keep you in the most aggressive position on the bike.
A Roval SLX 24 Disc wheelset with thru-axles is another area where Specialized have outdone themselves. These wheels are revered as incredibly rigid and durable on rougher terrain, and come in at an impressive sub-1600 grams. Perfect when paired with the FACT 11r carbon fork for more responsive steering.
Both front and rear thru-axles are a testament to the stiffness of the frame, ensuring there’s no flex over rougher surfaces in the wheels, too. The FACT 11r carbon fork furthers rigidity, but also allows for a small amount of vertical compliance to increase comfort.
Features
- Specialized FACT 11r carbon frame features a race-ready 'cross geometry, and comes equipped with thru-axles, 142mm rear spacing, and takes advantage of their highest quality carbon production methods in order to create a bike that's as responsive as it is lightweight
- The internally routed S-Works FACT carbon disc fork features a thru-axle design that increases steering response and rider input for the tight turns and the all-out efforts 'cross demands
- The Roval SLX 24 Disc wheelset features a sub-1600-gram weight, a 20-millimeter internal width, and an alloy construction that makes it a solid performer for any 'cross event
