FAQs
What is the main advantage of the EXP Ratchet system?
The EXP Ratchet system offers faster engagement (36 points), enhanced reliability due to fewer moving parts, and a lighter overall design compared to previous systems.
Can I use 6-bolt rotors with this hub?
Yes, but you will need a separate Centre-Lock to 6-bolt rotor adapter. The hub itself features a Centre-Lock mount.
What type of bearings does this hub use?
It uses custom-made DT Swiss steel bearings, known for their exceptional durability and smooth, drag-free rolling performance in all weather conditions.
Is this hub suitable for e-bikes?
While built for durability, the 240 EXP is primarily designed for traditional pedal-powered bicycles. Consult DT Swiss specifications for specific e-bike compatibility if needed.
How often should I service the ratchet mechanism?
Regular cleaning and lubrication of the ratchet mechanism are recommended, especially after riding in adverse conditions. Refer to the DT Swiss service manual for specific intervals and procedures.
What is the warranty period for DT Swiss 240 hubs?
DT Swiss typically offers a limited warranty on their hubs. Please refer to the official DT Swiss warranty information for the most accurate and up-to-date details.
Troubleshooting
Hub makes clicking or grinding noises.
Inspect the freehub body and ratchet mechanism for debris or damage. Clean and re-grease the ratchet system according to DT Swiss service guidelines. If issues persist, bearing service or replacement may be necessary.
Rear wheel feels loose or has play.
Check the thru-axle for proper tightness. Verify the integrity of the end caps and ensure they are correctly seated. The hub's bearing preload may need adjustment if applicable to the specific model.
Centre-Lock rotor feels loose.
Ensure the Centre-Lock lockring is tightened to the manufacturer's recommended torque specification (typically 40 Nm). Inspect the splines on both the rotor and the hub for wear or damage.

Setup, Compatibility & Care
Compatibility: This rear hub is designed for frames with a 142 x 12mm thru-axle. It features a Centre-Lock brake mount, which is compatible with Shimano Center Lock rotors. For riders using 6-bolt rotors, a separate Centre-Lock to 6-bolt rotor adapter is required. Ensure your wheel build adheres to the 24-hole specification for optimal performance.
Setup: Installation involves mounting the hub into your compatible frame and attaching your rotor using the Centre-Lock mechanism. Ensure the rotor is securely tightened according to manufacturer specifications.
Care: To maintain optimal performance and longevity, regularly clean the hub shell and freehub body of dirt and debris. Apply a light lubricant to the ratchet mechanism periodically, following DT Swiss recommendations. The custom DT Swiss bearings are sealed for protection but should be inspected periodically for signs of wear or damage. Avoid high-pressure washing directly at the hub bearings.
