Moutain bike carbon rim 27.5er(650B) MTB rim symmetric asymetric

Sakya Carbon 27.5er(650B) mountain bike carbon rim tubeless hookless symmetric or asymmetric

27.5er (650B) mountain bike wheel rims are the ideal size for mountain biking. Each rim is crafted from premium Toray T700 carbon fiber using a UD/3k weave, combining lightweight construction with impact resistance. Its optimized aerodynamic shape effectively reduces rider fatigue, perfectly balancing agility and handling. Suitable for various mountain, trail, and endurance riding scenarios, it allows riders of all levels to fully enjoy the diverse terrains.

Features:

• 27.5er(650B) specification, all-terrain capability with ease.
• Hookless rim design paired with tubeless tire system, doubling grip at low tire pressure.
• Symmetrical/asymmetrical options: Choose according to hub size and riding scenario to optimize wheel tension distribution and improve transmission efficiency and stability.
• Multiple spoke hole options: 24H/28H/32H/36H. Made with Toray T700+T800 carbon fiber, balancing strength and lightweight, impact-resistant, deformation-resistant, and suitable for complex mountain terrain.
• Diverse appearances: 3K/UD/12K/marble pattern, matte/glossy finishes available, balancing performance and personalization.
