Fjord Fitness XCT 300 Treadmill Blueprint

From Concept to Production

 A treadmill with power you never thought existed.

The Onyx. Pictures and videos cannot show how well built this treadmill is. Fjord set out on a mission to build a treadmill that rivals nothing that has ever been built. From the frame, rollers, motor, running surface and electronics no expense was spared, making this the last treadmill you ever purchase. Everything has been tuned and refined above and beyond a normal treadmill. This treadmills performance better rivals that of an Italian luxury vehicle than a treadmill.

Designed to be the best

Not only the most functional model in the Fjord line, the Onyx is also amazing in form as well. Designed with metallic silver and onyx black trim, you can really see we went all out on the Onyx Treadmill.
