SLR 1 40 650B 輪組系統
穩快駕馭
SLR 1 40 650b 輪組不僅具備與 700C 版本相同的輕量效率與空氣動力學優勢，更是專為較小車架尺寸所設計。這款高性能公路車輪組提供快速的加速和靈活的操控性，絕對是小騎士們挑戰遠大目標的完美選擇。
輕量化
這款輪組採用優化的碳纖疊層技術，並在關鍵受力點策略性地使用高抗拉強度碳纖維，打造出既堅固又輕量的結構。650b 版本的重量僅 1300 克，進一步減輕了整體重量，非常適合小型自行車和體重較輕的騎士。
高效能
SLR 1 40 650b 輪組搭載輕量化的碳纖維輪圈，專為較小的車架尺寸和騎士進行調校。其較小的輪徑和更短的輻條，能有效提升輪組的剛性與傳動效率。
自信駕馭
透過策略性優化的碳纖疊層技術，以高強度碳纖維強化了關鍵受力區域，在不增加重量的前提下提升了整體強度。無框鈎（hookless）輪圈設計形成了連續且堅固的結構，確保輕量與耐用性兼具。同時，22.4 mm的內寬和更寬的 2.8 mm胎壁，提供更好的輪胎支撐，讓騎士在公路及混合地形上都能擁有更自信的操控感受。
重點特色
1
Hookless Rim Design
Hookless rim design enhances overall durability and offers a wider inner rim width without adding weight.
2
OPTIMIZED CARBON LAY-UP
Optimized carbon layup features high-tensile strength carbon fiber placed at the most crucial points to provide stiff and lightweight wheels.
3
40MM RIM DEPTH
40mm hookless rim profile provides added aerodynamic advantage.
4
Dynamic Balanced Lacing (DBL)
Dynamic Balanced Lacing (DBL) technology makes a stiffer, more efficient wheel with outstanding power transfer. The enlarged DBL hub flange increases spoke bracing angles, boosting overall transmission and lateral stiffness for better power transfer.
5
2.8MM RIM BEAD WIDTH
2.8mm rim bead width enhances rim stiffness for better tire support when cornering.
6
22.4MM INNER RIM WIDTH
Designed for high volume road tires, the 22.4mm wide inner rim width creates a larger tire contact patch, resulting in better traction and impact absorption for more confidence and control.
7
GIANT LOW-FRICTION HUB
Giant low-friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction and lowering rolling resistance to minimize power loss.
