Product Information
Full details
The DT Swiss 350 Straight Pull rear hub is designed for cyclists seeking a dependable and high-performing rear wheel hub. Its core benefit lies in its reliability and excellent engagement thanks to the 36-tooth SL ratchets, derived from the renowned DT Swiss 240 hub technology. A minor caveat is its slightly higher weight compared to premium models due to less extensive machining. This hub offers a blend of DT Swiss's signature quality and refined performance for a wide range of road cycling applications.

FAQs
What is the main advantage of the 36-tooth SL ratchets?
The 36-tooth SL ratchets provide a faster and more direct engagement of the freehub when you start pedaling, leading to improved acceleration and responsiveness.
Is this hub suitable for tubeless setups?
This refers to the rear hub itself, which is the central component of the wheel. The suitability for tubeless setups depends on the rim and tire combination you build the wheel with, not the hub directly.
What is the difference between this hub and the DT Swiss 240 hub?
The 350 hub is based on the 240 design but typically has slightly less material removed through machining, making it a bit heavier but often more cost-effective while retaining excellent performance and durability.
Do I need special spokes for this hub?
Yes, this is a straight pull hub, meaning it requires straight pull spokes, not traditional J-bend spokes. Ensure your wheel builder is aware of this requirement.
What is the warranty period for DT Swiss hubs?
DT Swiss typically offers a limited lifetime warranty against manufacturing defects for their hubs. It's best to check the official DT Swiss website or your point of purchase for the most current warranty details.
Can I convert the freehub body to Campagnolo?
Yes, DT Swiss hubs are known for their interchangeability. You can usually purchase and swap the freehub body to be compatible with Campagnolo cassettes, though this specific variant is listed as Shimano Road.
How do I maintain the ratchet system?
The ratchet system requires periodic cleaning and lubrication with specific DT Swiss grease to ensure reliable engagement. It is recommended to have this serviced by a qualified mechanic or follow DT Swiss's specific maintenance guides.
Troubleshooting
Hub makes clicking noises when coasting
This is normal operation for a ratchet-based system. If the noise is excessively loud or irregular, it might indicate a need for servicing the ratchet mechanism.
Freehub body does not engage when pedaling
Check that the freehub body is correctly seated and the pawls/ratchets are clean and free to move. If the issue persists, the ratchet mechanism may require cleaning and lubrication, or servicing.
Rear wheel feels loose despite tightening quick release
Ensure the hub end caps are properly seated and the quick-release skewer is correctly installed and tensioned. Check that the hub bearings are not overly loose; adjust if necessary.
Bearings feel rough or not spinning smoothly
The bearings may need cleaning, lubrication, or replacement. This typically requires specialized tools and knowledge; it is recommended to have this serviced by a professional bike mechanic.

Setup, Compatibility & Care
Setup: The DT Swiss 350 Straight Pull hub is designed to be built into a wheel by a professional wheel builder. Ensure you select the correct flange spacing, spoke hole count (24 hole in this variant), and freehub body for your drivetrain (Shimano Road in this variant) and desired cassette. The hub uses a standard 130 mm quick-release spacing.
Compatibility: This specific model is configured for:
- Axle Standard: 130 mm Quick Release
- Drivetrain: Shimano Road (compatible with Shimano and SRAM 8/9/10/11 speed cassettes. For 12-speed, an appropriate freehub body may be needed).
- Spoke Type: Straight Pull spokes are required for this hub. Ensure your wheel builder uses the correct length and type of spokes.
Care: To maintain optimal performance and longevity:
- Cleaning: Regularly clean the hub exterior with a damp cloth. Avoid high-pressure water jets directed at the hub bearings.
- Lubrication: The ratchet mechanism is pre-lubricated. For servicing, DT Swiss recommends specific grease for the ratchets. Consult a professional or DT Swiss documentation for maintenance.
- Bearing Check: Periodically check for smooth rotation. If the bearings feel rough or gritty, they may require servicing or replacement by a qualified mechanic.
- Freehub Body: Keep the freehub body clean. Grit and dirt can impede the ratchet mechanism. Use a mild degreaser if necessary.
