Carbon Rim AR25-45 vs AR25-50 Selection Guide
These two U-shaped aerodynamic disc-brake carbon rims share an identical 25mm internal width. They feature the same tyre profile, full range of spoke hole options, three professional drilling patterns and dual-weight carbon layup configurations. The key distinction lies in aerodynamic gains, overall weight, crosswind handling and application scenarios brought by the 45mm and 50mm rim depths. Below is a comprehensive breakdown covering rim profile characteristics, suitable riding conditions, recommended spoke hole counts and drilling setups, as well as target rider groups to help you select the ideal rim quickly.
