FAQs
What is a thru-axle conversion?
A thru-axle conversion allows a wheel to be mounted to a bicycle frame using a solid axle that passes through the frame's dropouts and hub, providing increased stiffness and security compared to traditional quick-release skewers.
Is this kit compatible with all DT Swiss hubs?
No, this kit is specifically for DT Swiss rear ratchet EXP road hubs. Always consult the official DT Swiss Product Support Guide for specific compatibility information.
What does '142 x 12 mm' mean?
'142 mm' refers to the hub's overall width (and thus the frame's rear dropout spacing), while '12 mm' refers to the diameter of the thru-axle.
Can I use this with SRAM cassettes?
This specific kit is designed for Shimano Road HG cassettes. For SRAM compatibility, you would need a different freehub body or conversion kit.
Do I need special tools to install this kit?
Basic bicycle tools for hub service, such as cone wrenches and possibly seal presses, might be necessary. A torque wrench is recommended for final thru-axle tightening.
Where can I find the compatibility chart?
The compatibility chart can be found on the official DT Swiss website within their Product Support or Technical documents section, usually under wheelsets or hub conversion information.
Troubleshooting
Wheel does not fit into frame
Verify you have installed the correct 142 x 12 mm end caps. Ensure your frame is designed for a 142 mm thru-axle width. Double-check that your hub model is listed as compatible for this conversion.
Cassette does not engage or slips
Confirm that the hub is correctly converted for Shimano HG. Ensure the freehub body and cassette are properly seated and that the hub's ratchet mechanism is functioning correctly. Refer to DT Swiss documentation for EXP hub service if needed.
End caps feel loose
Ensure the end caps are fully seated against the hub bearings and that no debris is preventing a flush fit. Some end caps may have an o-ring for a snug fit; check if the o-ring is present and in good condition.

Care: Clean the end caps and hub body with a mild soap and water solution. Avoid high-pressure washing directly at the hub. Regularly check that the end caps are securely seated. Lubrication of freehub pawls should follow DT Swiss recommendations for EXP hubs.
