First Look: The New-Gen Sapim CX-Carbon 3.5 Ti Weighs Just 2.25g
Introduction
The CX-Carbon 3.5 Ti is not simply a lighter version (2.25g) of the existing CX-Carbon. Its updated hardware and symmetrical profile are also intended to make component integration and wheel building easier.
For wheel brands developing a new carbon-spoke wheelset, this could mean more flexibility in hub selection, a simpler lacing process, and a lightweight spoke option suitable for performance-focused products.
Details
The Sapim CX-Carbon is a high-performance carbon spoke designed to balance responsiveness, steering precision, and durability. We previously published a detailed look at its key features here.
Now, Sapim has developed a new-generation version: the CX-Carbon 3.5 Ti. It features a lighter titanium end-part configuration, a new symmetrical spoke profile, and updated hardware designed to make wheel building easier while maintaining high levels of aerodynamic performance, stiffness, and strength.
The CX-Carbon 3.5 Ti is currently available for offline ordering through Sapim's sales team. As a one-stop OEM/ODM wheelset supplier, NTP can also help source compatible wheel components and build sample wheelsets for brands developing new carbon-spoke wheels.
In this article, we take a quick look at what's new about the CX-Carbon 3.5 Ti and what it could mean for your next carbon-spoke wheel project.
Titanium and Steel End-Part Options
The CX-Carbon 3.5 Ti is available with two end-part options: titanium and steel. Both are available in black.
The titanium version is the standard configuration, bringing the spoke weight down to approximately 2.25 g per spoke at 260 mm. For wheel brands where ultimate weight reduction is less important, the steel end-part version provides a more cost-conscious option at approximately 2.9 g per spoke.
This gives wheel brands greater flexibility when balancing wheel weight, component cost, and the intended positioning of a wheelset.
Improved Hub Compatibility and Easier Wheel Building
One of the notable updates is the hardware design.
According to the product information provided by Sapim, the T-head hardware has been reduced from 4.5 × 5.5 mm to 3.65 × 5.5 mm, helping the spoke fit standard carbon-spoke hubs more easily. This can allow wheel brands to work with existing hub designs rather than developing a dedicated hub specifically for the new spoke.
The central blade profile has also been updated. Instead of the previous aero-wing shape, the CX-Carbon 3.5 Ti uses a 3.5 × 1.2 mm symmetrical profile. The symmetrical shape simplifies spoke orientation during lacing. Sapim describes the profile as optimized for both aerodynamic performance and wheel-building efficiency.
For wheel brands and custom builders, this is more than a small dimensional change. Easier spoke handling can help simplify the wheel-building process and make carbon-spoke assembly more straightforward.
Designed for High-Performance Racing Wheels
The CX-Carbon 3.5 Ti is designed around a combination of low weight, aerodynamic performance, stiffness, and toughness.
Sapim specifies a maximum strength of more than 3500 N, while the optimized fiber volume is intended to provide high lateral rigidity and power transfer. The product sheet also highlights side-impact resistance for demanding racing applications.
For performance-oriented wheel brands, the combination of a lightweight titanium configuration and a wider 3.5 × 1.2 mm symmetrical profile makes the CX-Carbon 3.5 Ti an interesting option for developing lightweight carbon-spoke wheelsets.
