SpeedX Gravel Tire 700 x 45 Dual Zone Casing

Delium Tire SpeedX Gravel Tire 700 x 45 Dual Zone Casing pushes performance beyond the pavement, delivering the perfect balance of speed and control for riders who demand versatility on mixed terrain. This tire is built for hard-packed dirt, loose-over-hard, and dusty gravel adventures where predictability and grip matter most.

The SpeedX features a fast-rolling center tread that keeps momentum high on straightaways, while its aggressive side knobs dig in with confidence when the trail turns rough or the corner tightens up. The Dual Zone Casing combines durability and comfort, giving riders a supple yet stable ride with fewer flats and more fun miles. Add in the dual compound rubber—50a for grip and 62a for longevity—and you’ve got a tire that’s engineered for both speed and staying power.

Whether mounted on an e-gravel bike or a classic drop-bar rig, the ECE-R75 certification ensures it’s ready for the demands of modern electric-assist riding.
