Service / Ownership Context
These bearings are press-fit into the hub shell or freehub body. Proper bearing removal and installation tools are required (hub press or arbor press). Improper installation risks bearing and hub damage. Bearings typically fail from water ingress, grit contamination, or long service intervals.
Fit & Use Signals
- Good Fit: Your DT Swiss front hub calls for a 17×26×5 mm bearing.
- Good Fit: You are servicing DT Swiss Spline 1200, 2nd Gen 1501, or DiCut disc wheels (front hub).
- Not A Fit: Your hub uses a different bearing size.
- Not A Fit: You expect this to be a wheel or complete hub — this is a **single bearing**.
- Not A Fit: You want a full bearing kit.
DT Swiss 6803 (17×26×5 mm) is commonly used in front hub bearing positions on higher-end road and mountain wheel families like Spline 1200, 2nd Gen 1501, and DiCut disc wheels. Always verify the bearing size by measuring your old one before ordering — DT Swiss hubs can use multiple sizes depending on model and position. Installing these bearings correctly requires proper tools — a press is essential. Do not attempt hammer installation; damaging seals and races makes the hub noisy and short-lived. For two bearing front hubs, you’ll need two of these. For rear hubs, check spec — they often use larger sizes like 6904, 6902, or 6805. Bearing only — no wheel, axle, or hub included.
