The CS-A/T 38 is a high-performance carbon fiber spoke, centered on the core advantages of lightweight and rugged durability, ideal for upgrading various bicycle wheel sets. Its main body is crafted from carbon fiber, with a single weight of just 3g and a width of 3.8mm. It is paired with stainless steel spoke threads and spoke caps, and manufactured via a glue-free mechanical locking pultrusion process—ensuring a stable structure and consistent quality across all units.

Boasting a matte finish, the CS-A/T 38 combines scratch resistance with a premium texture. It also comes in two styles (round-head and T-head) to flexibly fit different hub specifications. Beyond significantly reducing wheel inertia and boosting riding efficiency, the CS-A/T 38 resists daily wear and harsh environmental damage, catering to the multi-faceted needs of professional riders and cycling enthusiasts for performance, lightweight design, and compatibility.

Product Features and Advantages

Lightweight & High-Efficiency, Enhancing Riding Performance:

With an ultra-light carbon fiber body (only 3g per spoke) and precise 3.8mm width, it significantly reduces wheel rotational inertia. This makes startup and acceleration lighter, cuts down power consumption during climbing, and is especially suitable for scenarios with high lightweight requirements such as road bikes and racing bikes, directly boosting riding efficiency and speed potential.

Tough & Durable, Balancing Reliability and Longevity:

Material Complementarity: The carbon fiber body boasts excellent tensile strength, resisting impact from bumps during riding; the stainless steel spoke threads and caps are corrosion-resistant and rust-proof, capable of withstanding harsh environments like rain and mud, and preventing accessory aging and damage.

Process Support: The glue-free mechanical locking pultrusion process not only eliminates the risk of loosening caused by glue aging but also ensures consistent quality of bulk products, extending the overall service life of the spokes and reducing subsequent maintenance costs.

Flexible Adaptation, Meeting Diverse Needs:

Available in two styles (round-head and T-head), it can fit most regular hubs and special-spec hubs (such as high-profile carbon wheels and specific mountain bike hubs) without additional modifications, offering wide compatibility. Combined with a matte finish, it not only features a premium texture but also is scratch-resistant and easy to clean, leaving no obvious marks in daily use, thus balancing practicality and aesthetics.

Application Areas

Application areas for theCS-A/T 38 carbon spoke wheel:

• Round-Head Compatibility:

Mainly compatible with "straight-pull hubs" and "standard-hole hubs", covering most entry-level to advanced road bike and mountain bike hubs (e.g., Shimano 105 series, SRAM Rival series hubs) as well as some urban commuter bike hubs. It fits the industry’s universal standard for hub hole diameter (common 6mm-8mm hub holes) and can be directly installed without additional hole expansion or modification.

• T-Head Compatibility:

Specifically designed for "disc brake hubs", "hubs for high-profile carbon wheels", and "special-shaped hole hubs" (e.g., Campagnolo Bora series carbon wheel hubs, DT Swiss 350 disc brake hubs). The T-shaped head structure can tightly fit into the grooves inside the hub holes, preventing spoke rotation and displacement—making it especially suitable for high-performance wheel sets that require higher connection stability.
