Rim Brake

Obsidian-patterned brake surface boosts friction and drains water well, ensuring stable braking on dry/wet roads; brake surface laser logo is customizable. Wheel set weighs 1346±30g (lightweight); carbon rim + carbon spokes (only 2g per spoke) deliver high rigidity for fast power transfer. Hub works with multiple shifting system specs; supports 28-45C tire size & 110-125PSI tire pressure, fitting all road cycling scenarios. Carbon spoke appearance and coating can be customized as needed to meet personal style preferences. 50mm medium-high rim reduces wind resistance; 28mm external width fits wide tires and is less sensitive to crosswinds.

Excellent rim protection: Soft cork material reduces wear on carbon rims, extending their lifespan. Superior heat dissipation: Quickly dissipates heat to prevent carbon rims from overheating and "burning". Stable braking performance: Minimal performance loss in wet conditions, ensuring reliable braking. Quiet and comfortable: Low friction noise, enhancing riding experience. Great compatibility: Specifically designed for carbon rims, fitting most calipers.
