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.

Techs & Features

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

Hookless rim design enhances overall durability, offers a wider inner rim width without adding extra weight and also helps create a more round tire shape providing superior grip and handling as well as added sidewall support when cornering. Additionally, without the rim hook to “push” the tire bead inward, 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.

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

Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
