Feature:

The design ensures a seamless rim-to-tire transition for tires ranging from 40-60mm, enhancing aerodynamics. It also offers casing support for lower pressures, improving grip, comfort, and reducing rolling resistance.

Expanding to 32mm internally and 40mm externally, the rim's width closely matches that of the tire, ensuring a smooth transition. This optimizes laminar airflow across the rim-tire system, effectively reducing drag.

Note:

We provide custom assembly wheels building service because have many configurations, so the weight of the wheels need be calculated.

If you need lightweight wheels, please choose lightweight rims, hubs, and spokes.
