Specialized Crux Frameset

The Crux is a versatile gravel platform that bridges the gap between a lightweight road bike and a rugged adventure machine. It excels on mixed-surface rides, fire roads, and technical gravel, offering a stiff, responsive feel that handles long days in the saddle with ease.

The frame is designed for significant versatility, accommodating tires up to 700c x 47mm or 650b x 2.1 inches. This allows you to tailor your setup for everything from fast, hard-packed gravel to rougher, more technical terrain.

The Crux frameset utilizes a standard threaded BSA bottom bracket with a 68mm width. This is a reliable, user-friendly choice that simplifies maintenance and helps prevent creaking issues often associated with press-fit systems.

While some parts might carry over, you will need to ensure compatibility with the disc-only brake system, 12x100mm front and 12x142mm rear thru-axle spacing, and the specific headset dimensions. It is best to verify your current drivetrain and wheelset specs against these standards before starting your build.

Yes, the frame features three water bottle mounting positions, providing ample hydration capacity for long-distance adventures. It keeps the aesthetic clean while ensuring you have the utility needed for extended rides.

The FACT 10r carbon frame is engineered to balance stiffness and compliance. This means you get efficient power transfer when you pedal hard, but the material also helps dampen road vibration, keeping you comfortable on rougher surfaces.
