Giant SLR 1 42 Disc Carbon Rear Wheel

The SLR 1 42 and 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 and SLR 1 42 Disc bring outstanding performance at no compromise.

Highlights

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.

Hookless Design

• Lightweight Performance: Compared with hook-type rims, Giant’s new hookless design has a wider inner rim width, allowing a smaller, lighter tyre to have the same volume as a larger, heavier tire, resulting in a lighter overall weight.
• Enchanced 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 tyre shape that provides superior grip and handling as well as added sidewall support when cornering.
• Aero Advantage: Without the rim hook to “push” the tyre bead inward, Giant's hookless rim design offers a more seamless airflow between the tyre 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 long-term durability and braking performance.

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.

Optimised Carbon Layout

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.

Features

• Hookless rim design enhances overall durability and offers a wider inner rim width without adding weight
• Optimised carbon layup features high tensile strength carbon fibre placed at the most crucial points to provide stiff and lightweight wheels
• Low friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction, lowering rolling resistance and minimising power loss
• Dynamic Balanced Lacing (DBL) ensures spokes are set for optimal tension when pedalling, resulting in enhanced durability and transmission efficiency
• The enlarged DBL hub flange increases spoke bracing angles, boosting overall torsional/transmission and lateral stiffness for better power transfer
• 42mm deep all-round rim profile with an updated inner width offers better support for today’s higher volume road tyres
