SLR 2 42 Disc

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.

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.
