Spoke Tension Balance
The spokes of the rim brake version's rear wheel and the disc brake version's front and rear wheels all use a 2:1 flat braid method to reasonably distribute spoke tension, making the pedaling transmission more powerful.
The rear wheel drive side spoke tension is 120kgf ± 10%
Non-drive side spoke tension is 100kgf ± 10%
Compared with the 1:1 weaving method, the balance is improved by about 100%
Wider And More Aerodynamic
All Classic Pro series rims are designed with an outer width of 28mm and an inner width of 21mm. The 28mm outer width rim design is wider than most current wheel products. When used with 25c and 28c tires, it can create a flatter aerodynamic surface and reduce air resistance.
NBK Ceramic Bearings
The Classic Pro comes with ceramic bearings, Ceramic bearings use ceramic races, which can be lighter in weight and have less rotational friction resistance. The surface of the ceramic material is smooth and the friction coefficient is low, which allows the bearing to reduce energy loss during operation and improve your riding efficiency.
