S-Works Crux Frameset

What Our Gearhead Experts Are Saying:

"The S-Works Crux is stupid light-lighter than most road frames but it eats up rough gravel. I built mine with a wireless drivetrain and still came in under UCI weight limits. It climbs like crazy, corners tight, and I've had zero tire rub with 45mm tires. Honestly, I wouldn't change a thing."

The S-Works Crux Frameset is engineered for riders chasing podiums and peak performance on the gravel circuit. At just 725g (S-Works 12r) for the frame, it's the lightest gravel-specific platform in existence, taking cues from Specialized's revolutionary Aethos road frame to achieve minimal weight with uncompromised ride quality. Paired with a full carbon S-Works fork, it offers unmatched compliance without sacrificing stiffness when sprinting or climbing out of the saddle.

This frame supports up to 47mm tires on 700c wheels or 2.1in on 650b setups, matching the Diverge in clearance but far exceeding it in responsiveness and speed. It's ready for mechanical or electronic drivetrains, thanks to clean internal routing and a BSA threaded bottom bracket that simplifies maintenance. With performance-tuned geometry and a rider-first engineered frame layup, the Crux is as comfortable on a 200-mile gravel epic as it is toeing the start line.

For racers and dream-build enthusiasts alike, this is the blueprint for a featherlight gravel machine that's ready to take on anything.

Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
