The SLR 1 40 650b WheelSystem delivers the same lightweight efficiency and aerodynamic advantages as its 700C counterpart, but is specifically designed for smaller frame sizes. This performance road wheel offers rapid acceleration and nimble handling—making it the perfect choice for small riders taking on big challenges.

LIGHTWEIGHT

Optimized carbon layup with high-tensile-strength carbon fiber strategically places reinforcement at critical stress points, creating a stiff, lightweight structure. At just 1300g, the 650b option further reduces the weight, making it ideal for smaller bikes and lighter riders.

EFFICIENT

The SLR 1 40 650b WheelSystem features a lightweight carbon rim specifically tuned for smaller frame sizes and riders. Its smaller diameter and shorter spokes offer increased stiffness and better transmission efficiency.

CONFIDENT

A strategically optimized carbon layup reinforces key stress zones with high-tensile-strength fibers, enhancing strength without adding weight. The hookless rim design forms a continuous, robust structure for lightweight durability, while the 22.4mm inner width and wider 2.8mm bead provide better tire support and more confident handling on road and mixed terrain.

Technológie

Optimized Carbon Lay-Up

Giant optimized reinforced layup places extra maximum-strength carbon fiber only where needed, creating a robust structure at minimal weight.

Dynamic Balanced Lacing

Since its introduction in 2015, Dynamic Balanced Lacing (DBL) has been the cornerstone of Giant WheelSystems. DBL ensures that spokes are set for optimal tension when under dynamic load, resulting in enhanced durability and pedaling efficiency. The enlarged DBL hub flange also increases the spoke bracing angles, which boosts overall torsional/transmission and lateral stiffness for better power transfer and more stable sprinting.

Hookless Rim Design

Dizajn ráfika bez háčikov zvyšuje celkovú životnosť, ponúka širšiu vnútornú šírku ráfika bez zvýšenia hmotnosti a tiež pomáha vytvoriť okrúhlejší tvar pneumatiky, ktorý poskytuje vynikajúcu priľnavosť a manipuláciu, ako aj pridanú podporu bočnej steny v zákrutách. Navyše bez toho, aby háčik ráfika „tlačil“ pätku pneumatiky dovnútra, ponúka bezháčkový ráfik plynulejšie prúdenie vzduchu medzi pneumatikou a bočnou stranou ráfika, čo má za následok menší odpor a lepší aerodynamický výkon v porovnaní so štandardnými hákovými ráfikmi.

Low Friction Hub

Giant uses precision machined internals to eliminate the power loss that occurs through the pressure from the hub internals on the bearings, reducing friction and minimizing rolling resistance.

Tubeless System

Technologie Giant Tubeless System nabízí kompletní řešení pro bezdušová kola. Zahrnuje vše, co je potřeba – zapletená kola, pláště, ventilky a těsnicí tmely, čímž eliminuje potíže s instalací a kompatibilitou, a vy tak můžete jezdit bez obav a omezení.
