Description
Specialized Crux 5 Comp Gravel Bike
The Crux 5 Comp gravel bike offers an accessible entry point into the world of elite gravel racing without sacrificing the core DNA of the fastest frame in the category. Built around the same FACT 10r carbon frame as its higher-tier siblings, this bike maintains a lightweight profile with a frame weight of only 897 grams. By prioritising a chassis that mimics the responsive handling of a Tarmac, the Crux 5 Comp ensures that every ounce of rider input is converted into immediate forward motion. At a total weight of 8.89 kilograms, it provides a nimble and spirited ride that excels on steep climbs and technical terrain, making it the perfect partner for riders looking to elevate their performance on race day.
Aerodynamic Performance and Robust Reliability
Efficiency is at the heart of the Crux 5 design, and the Comp model utilizes smart component choices to maximize speed against the wind. Featuring a specialized Rapide stem paired with a race-ready alloy handlebar, the cockpit provides a stiff and dependable interface for aggressive sprinting and high-speed descents. The DT G-500 wheelset is chosen for its remarkable durability and smooth-rolling performance, capable of absorbing the chatter of rough fire roads while maintaining a fast aerodynamic profile. This focus on real-world speed ensures that you spend less time fighting resistance and more time gaining ground, leading to a lower overall time to finish on even the most demanding courses.
Seamless Shifting and Confident Handling
The drivetrain is powered by the SRAM Rival AXS XPLR group, bringing the precision of wireless electronic shifting to a broader range of competitive cyclists. This system eliminates the worry of cable stretch or contamination, providing crisp and reliable gear changes in the heat of competition. With a gearing range specifically tailored for the undulations of gravel racing, you will always find the right rhythm to maintain your momentum. When combined with the frame’s ability to handle dirt with surgical precision, the Crux 5 Comp delivers a ride quality that is both stable at speed and agile in the corners. It is a robust, high-performance machine designed to get you to the finish line faster than the competition.
