SLR 1 65 WheelSystem
Aero Gains
The SLR 1 65 WheelSystems are lightweight, aero carbon wheels that deliver premium aero gains to all riders. Featuring a 65mm deep rim profile with a contemporary 22.4mm inner width, SLR 1 65 WheelSystems not only provide aerodynamic benefits but also better support for today’s higher volume tires. With hookless rim design and optimized carbon layup to ensure robust structure with minimal weight, as well as low friction hubs and Dynamic Balanced Lacing technology to maintain maximum power efficiency, the SLR 1 65 offer riders maximum aero efficiency with no weight penalty.
Key Performance Factors
Lightweight and Strong
Giant’s hookless rim design enhances overall durability and offers wider inner rim width, while an optimized carbon layup places carbon fiber at the most critical points to create an exceptionally robust structure at a minimum weight
Maximum Power
With Giant’s Dynamic Balanced Lacing (DBL) technology and low friction hub, the SLR 1 65 features exceptional transmission efficiency and drastically reduced rolling resistance
Aerodynamic
A 65mm-deep rim profile with an updated 22.4 inner width not only reduces front air drag but also provides a smoother airflow transition from tire to rim, reducing overall aerodynamic loss
Highlights
Behind the outstanding performance of the new Giant SLR 1 65 WheelSystems are several innovative technologies that deliver lightweight aerodynamic advantage, and confident handling.
1
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.
2
Hookless Rim Design
LIGHTWEIGHT PERFORMANCE
Compared with hook-type rims, Giant’s new hookless design has a wider inner rim width, allowing a smaller, lighter tire to have the same volume as a larger, heavier tire, resulting in a lighter overall weight.
ENHANCED DURABILITY
Giant’s hookless rim design is realized through an innovative manufacturing process that results in a more continuous carbon fiber structure. This process enhances durability and increases impact resistance with no weight penalty.
CONFIDENT HANDLING
Hookless rims help create a more round tire shape that provides superior grip and handling as well as added sidewall support when cornering.
AERO ADVANTAGE
Without the rim hook to “push” the tire bead inward, Giant's hookless rim design offers a more seamless airflow between the tire and the sidewall of the rim, resulting in less drag and improved aero performance when compared to standard hook-type rims.

High TG Resin
Giant’s proprietary High Glass Transition Temperature (Tg) resin helps produce a brake track that withstands the higher heat caused by heavy rim braking, enhancing the rim’s longterm durability and braking performance.
4
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.
5
Optimized Carbon Layup
Through high-tensile strength carbon fiber placed at the most crucial points and tested with Finite Element Analysis (FEA), Giant’s engineers overcame the challenge of building wheels that are as durable as they are lightweight. With industry leading stiffness, ride compliance and strength all at the lightest weight possible, the new SLR WheelSystems are fast and strong.
