ArcX 255g 超轻 29er 碳纤维 36x24.5mm 内宽 30mm 无内胎 无钩 不对称山地车轮圈，电动自行车轮圈

选择合适的XC轮圈的建议：

• 对于常规XC运动，可选择255克版本。
• 这是XCO世界杯运动员信赖的轮圈。但对于XCO，请选择重量大于285克的版本——它会更耐用。

Optimized Force Transmission & Enhanced Structural Integrity

The recessed spoke holes embed the tension point deeper into the rim structure, allowing spoke tension to follow a more natural load path.

This significantly reduces stress concentration around each hole, improving fatigue resistance — especially important in carbon fiber rims.

Improved Spoke Hole Angle Alignment

The inward curvature allows spoke holes to better match the natural spoke angle from the hub, reducing friction and stress between spokes and the rim wall.

This results in smoother wheel building, more balanced tension, and longer-lasting wheelsets.

Potential Weight Optimization

When properly engineered, the recessed design increases local stiffness without requiring thicker wall sections.

This allows for more efficient material use, enabling overall rim weight reduction while maintaining strength.

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.
