Specialized S-Works Crux Disc Cyclocross Bike 2020
Faster, lighter, stiffer, the full carbon Specialized S-Works Crux Disc Bike is the ultimate cyclocross podium hunter, refined and engineered to deliver everything you need for hard and fast racing. A slightly lowered seat collar delivers a reassuring amount of additional compliance to help dissipate harsh bumps and the 33mm tyres fit the frame with plenty of room to spare and will prevent mud from clogging up your performance. Tube shapes deliver stiffness in all the right areas and the flat-bottom top tube is part of a larger frame triangle that makes the bike easier to shoulder when negotiating unrideable sections or when hopping barriers. A lower bottom bracket and sharp front end are part of the race geometry that feels secure in corners yet still nimble and responsive.
The high-performance specification is built with top of the line Shimano Dura-Ace Di2 electronic shifters and Di2 XTR derailleur for the ultimate gear shifting response. Roval CLX 50 disc carbon wheels with CeramicSpeed bearings and an S-Works single-sided power crank round off this quality bike.
Features
- Roval CLX 50 Disc carbon fibre wheelset
- Shimano Dura-Ace and XTR Di2 components
- CruX frame now comes in around a scant 900 grams for a 56cm
- Large opening to the front triangle and a flat bottom for ease of shouldering
- Plenty of tyre clearance for efficiently shedding mud
