Specialized S-Works Crux 5 FACT 12r carbon frameset with UDH and 55mm tire clearance
What Our Gearhead® Experts Are Saying:
"The FACT 12r layup pulls tube shapes directly from Tarmac SL8 wind tunnel development. At elite gravel race speeds the aero work is doing real, measurable work. This isn't a road race geometry adaptation, it's a purpose-built race platform with a gravel-specific tire clearance story underneath it."
Why We Like It
The Crux 5 opens tire clearance to 55 millimeters, up from the Crux 4, without geometry compromises. At race pace on rough terrain, wider tires at lower pressure hold momentum through sections where a narrower setup scrubs speed. The subtle geometry changes Specialized made to accommodate it also sharpen handling confidence across the size run.
