Specialized Crux Expert Disc Gravel Bike 2022
New and improved, the Specialized Crux Expert Disc Gravel Bike is in a class of its own when it comes to weight, tyre clearance and capability. Labelled as the ultimate expression of gravel performance, this latest revision of the Crux channels the Aethos design process to drop the frame weight down to just 825 grams for this FACT 10r carbon model. The nimble geometry is inspired by the Crux’s cyclocross race heritage and sees a long reach paired with a reduced stack height to deliver fast, reactive handling.
Equipped with 700c wheels and 38c tyres as stock, this model has a maximum clearance of 47c, or 2.1” when paired with the smaller 650b wheel standard. This enhances the frame’s capability, ensuring versatility for a range of ride styles and terrains. The carbon layup is highly responsive yet delivers fatigue-reducing vibration-damping suitable for comfort over long distances.
Optimised for mixed terrain performance, the Roval Terra C wheelset is ideal for fast-paced adventure riding. They are tubeless-ready and are the perfect pairing for the equipped Specialized Pathfinder pro tyres, delivering optimal grip across a range of surfaces. The SRAM Rival eTap AXS drivetrain delivers state of the art wireless shifting across its wide 12-speed range and can be customised through the accompanying SRAM mobile app to personalise your shifting experience. Powerful SRAM hydraulic disc brakes provide supreme control on steeper gradients, and the Supacaz Super Sticky Kush bar tape adds a premium, aftermarket touch.
