Specialized Crux Pro Disc Gravel Bike 2022
As the amalgamation of years of design and athlete-led research, the Specialized Crux Pro Disc Gravel Bike is a reactive and confident choice for discerning racers seeking unrivalled performance. Taking notes from the Aethos playbook, this latest revision of the Crux is the lightest to date, with the FACT 10r carbon composite frame weighing in at a mere 825 grams. It is race-ready straight out the box with its premium specification seeing truly wireless SRAM AXS shifting, ultralight Roval Terra CL wheels and powerful SRAM Force eTap hydraulic disc brakes.
Lightweight, capable and responsive are three words that sum up the Crux Pro experience. Wide tyre clearance mirrors the Diverge gravel bike, and the supple frame effectively damps vibration to keep you calm and composed when every second counts. Underneath the stylish paintwork lies the source of the Crux’s fabled ride quality. The sleek carbon tubes have an optimised stiffness to weight ratio without compromising durability to cope with the harsh realities of gravel racing.
The combination of an ultralight frameset and wide tyre clearance is a potent one, with the ability to run up to 700c x 47c or 650b x 2.1” rubber affording versatility seldom seen on other gravel models. The fit is race-inspired and features performance gravel geometry that combines a long reach with a low stack height to deliver balanced weight distribution and lightning-fast handling.
The parts list sees a host of components that favour performance and durability. State of the art shifting is supplied by the SRAM Force eTap AXS drivetrain, which can be customised through the accompanying SRAM mobile application to meet your preferences. Roval Terra CL 700c wheels deliver fast-rolling performance and rapid acceleration and are clad with the Specialized Pathfinder Pro 38c tyres to deliver exceptional grip on a range of surfaces.
