The internal width of the rim of 19 mm allows the mounting of tires with 23 mm, 25 mm and 28 mm. The rim design allows for maximum aerodynamic penetration because the wind, when acting on the rim at an angle between 12° and 19°, gives the triathlete momentum. The aero-elliptical cross-section of the 18 front spokes drastically reduces rolling resistance. Proven USB tapered bearing cup system ensures ceramic bearings glide properly Game weight: 1496 grams.
