With a rim profile of 45 mm and a set weight of only 1200 grams, the Artech 4.A combines ultra lightweight with superb aerodynamics and cross-wind stability. The ultimate wheelset for climbing the Alps and Pyrenees facing unexpected cross-winds, both for paved and smooth gravel roads.

Besides an extreme low weight and aerodynamic advantage, the Artech 4.A  provides a high lateral stiffness and doesn’t compromise in durability. The 25 mm internal width hooked tire bed is aerodynamically optimized for 30 mm road and off-road gravel tires.
