Crux 5 | The Equation of Gravel Speed

Gravel racing has changed. What used to feel like an endurance event has become a full-speed race, with stronger athletes, higher speeds, sharper tactics, and bigger consequences for every equipment choice.Crux has always been loved for its light weight, lively ride, and pure race feel. But as gravel racing got faster, Specialized had to answer a harder question: how do you make Crux faster without losing what riders already love about it?In this episode, guest host Ben Edwards sits down with Leo Cadena, Doug Russell, and Alex Jerome just north of Barcelona to go inside the creation of Crux 5. They discuss the evolution of gravel racing, the shift from cyclocross roots to a dedicated gravel race platform, and the engineering work behind making a bike that is not simply light or aero, but faster against the only metric that matters: time to finish.They get into Specialized’s equation of speed, Formula 1 style simulation, moving-leg mannequin wind tunnel testing, race-course telemetry, tire rolling resistance, 55 mm tire clearance, the new Terra cockpit, Terra wheels, and the challenge of preserving the Crux ride feel while building a faster bike for modern gravel racing.This episode covers:How gravel evolved from an event into a raceWhy Crux 5 was built as a dedicated gravel race bikeThe equation of speed and why time to finish matters mostHow Specialized balances aero, weight, rolling resistance, and ride qualityWhy bike-only aero testing does not tell the full storyHow moving-leg mannequins make wind tunnel testing more realisticHow race telemetry from Unbound and other courses shapes product decisionsWhy tire choice and tire clearance can decide a raceThe role of 50 mm and 55 mm tires in modern gravel performanceHow Crux 5 became 15.2 watts faster than Crux 4Why the new Terra cockpit matters for comfort, control, and aero efficiencyHow Crux 5 keeps the light, lively ride that made Crux so lovedWhat simulated Unbound time savings reveal about real race performanceWhy the future of gravel race bikes is about systems, not isolated numbersGuests:Leo Cadena, Doug Russell, Alex JeromeGet More from SpecializedTikTok: @specializedbicyclesInstagram: @iamspecializedSpecialized MTB Instagram @iamspecialized_mtbSpecialized Factory Racing Instagram: @specialized_factoryxcFacebook: specializedbicyclesOutride: @outride
