Classic PRO D28-45 Disc Brake Black Decals PILLAR WING21 Spokes

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 commonly used in road bike races. They’re lighter in weight and have less rotational friction. You can go faster with lower rolling resistance.

Spokes And Hubs

The hubs are upgraded from the base Classic’s steel to ceramic bearing hubs. The spokes are also upgraded to straight-pulled spokes and the disc brake version has Pillar Wing-21 spokes. These spokes have more direct power transfer and tensile strength.

Intergral Rim Brake Surface Design

The rim features a one-piece hollow rim design with an integrated braking surface for enhanced structure and performance. You don't have to worry about the braking surface peeling. The K-line brake edge dissipates heat and drains water, eliminating the risk of brake lock and reducing the braking surface temperature.
