FAQs
What are the exact dimensions of this DT Swiss bearing?
This is a standard 6803 bearing with a 17mm inner diameter (ID), a 26mm outer diameter (OD), and a 5mm thickness.
How do I know if this bearing is compatible with my DT Swiss wheel or hub?
You must verify your specific DT Swiss wheel or hub model against the official DT Swiss compatibility charts or service manuals. This bearing is a replacement part and not universally compatible with all DT Swiss products.
Can I use a generic 6803 bearing instead of a genuine DT Swiss part?
While a generic 6803 bearing shares the same dimensions, a genuine DT Swiss bearing is manufactured to meet their specific quality and performance standards for their hubs and wheels. Using a non-genuine part may affect performance and longevity.
What tools are needed to replace a hub bearing?
Replacing hub bearings typically requires a bearing press kit, a suitable bearing puller, and possibly a socket set or Allen keys depending on your specific hub model. Professional bicycle mechanic tools are often best.
How often should I replace my hub bearings?
The replacement interval varies greatly depending on riding conditions, mileage, and maintenance. Inspect bearings regularly for roughness or play, and replace them as needed, typically every few thousand miles or when performance degrades.
What causes a hub bearing to fail prematurely?
Premature failure can be caused by water ingress, dirt contamination, lack of lubrication, improper installation (over-tightening or uneven seating), or excessive impact loads.
Troubleshooting
Bearing feels rough or not spinning freely.
The bearing may be contaminated or worn. Clean the exterior and check for smooth rotation. If roughness persists, replacement is recommended. Ensure it is properly seated in the hub.
Hub has play or looseness even after bearing replacement.
Check that the bearing is fully seated and that any hub end caps or seals are correctly installed. Ensure the hub's pre-load adjustment (if applicable) is set correctly.
Bearing installation is difficult or causes damage.
This usually indicates an incorrect bearing size for the hub or improper technique. Double-check compatibility and use appropriate bearing press tools. Seek professional assistance if unsure.

Setup, Compatibility & Care
Compatibility: This is a genuine DT Swiss 6803 bearing with specific dimensions: 17mm inner diameter, 26mm outer diameter, and 5mm thickness. Before purchasing, always consult the official DT Swiss website or your wheel/hub's service manual to confirm compatibility with your specific model. Incorrect sizing will prevent installation and can damage components.
Setup: Installation typically requires specialized bearing presses and tools to avoid damaging the bearing or the hub shell. If you are not experienced with bicycle hub maintenance, it is recommended to have a professional bicycle mechanic perform the replacement.
Care: To maximize the lifespan of your bearing, keep it clean and properly lubricated. After riding in wet or dirty conditions, clean the exterior of the bearing and hub. Periodically, depending on riding conditions, the bearing may require re-greasing or replacement. Avoid high-pressure washing directly at the bearing seals, as this can force contaminants inside.
