SLR 1 42 Disc WheelSystem
All-Around Speed
The SLR 1 42 Disc WheelSystems are efficient lightweight all-around carbon road wheels that bring premium-level performance to all riders. Featuring hookless rim design and optimized carbon layup to ensure a robust yet lightweight structure, contemporary wider inner width, as well as low friction hubs offering low rolling resistance and Dynamic Balanced Lacing (DBL) technology to maintain maximum power efficiency, the SLR 1 42 Disc bring outstanding performance at no compromise.
Key Performance Factors
Lightweight and Strong
Giant’s hookless rim design enhances overall strength 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 technology and low friction hub, the SLR 1 features superior transmission efficiency and drastically reduced rolling resistance
Confident Handling
Hookless rim design’s wider inner width not only provides better support for a higher volume tire but also forms a rounder tire shape for better cornering stability.
Highlights
Behind the outstanding performance of the new Giant SLR 1 42 Disc WheelSystems are several innovative technologies that deliver lightweight advantage, max power transfer 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.

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.
4
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.
