DT Swiss believes in the art of engineering and strive for sophistication in the product development process. Our guiding idea is to constantly push barriers with our inhouse developed technologies.

With the 350, reliability meets simplicity, exactly according to this credo the 350 hub was developed. The simultaneous engagement of the ratchets and the resulting large contact area provides the aimed reliability. The plugged construction allows easy maintenance without the need of tools. Adaptation to different axle standards or modification of the engagement angle is also possible in a few manual steps.

SAPIM CX-Ray Aero (elliptical)

The CX-Ray still receives one of the best results in fatigue testing of any spoke. Its unique strength and flexibility make the CX-Ray suitable for most bicycle disciplines. The middle section of the spoke is drawn then pressed in a special mold to form its specific profile. CX-Ray spokes are used by top bike racers and triathletes around the world. Even downhillers use them, recognizing their strength and flexibility. Special alloy treatment and sophisticated production make this all possible.

  • Almost as light as Titanium.

  • More long lasting than any other spokes on the market.

  • Extremely high fatigue test results.

  • Special alloy treatment and sophisticated production.

  • The best aerodynamic eliptic spoke available.

  • Produced from high-tensile, fatigue-resistant 18/8 stainless steel conforming to the Sapim quality standard specifications.

SAPIM secure lock alloy black 4mm

Material: alluminium

Aluminum is the material of choice for higher performance. For this purpose, Sapim has chosen the highest aluminum grade possible (7075 T6) for this sort of usage. It combines light weight, strength and corrosion resistance. The anodized surface treatment provides various color possibilities.

Sapim’s state of the art manufacturing process ensures the best quality available. As a consequence Sapim’s Aluminum nipples has become the benchmark in the market.

​The coating is applied on the thread and on the nipple. Friction between both spoke and nipple and rim and nipple is significantly reduced. Coating also seals the surface reducing corrosion. This is now standard in Sapim’s production.
