This is a genuine DT Swiss 6904 cartridge bearing, sized 20×37×9 mm, designed for use in specific DT Swiss hubs. Sold **per bearing**—not a set. These are the same spec bearings found in many DT Swiss 240S-level hubs and other DT Swiss wheel models that accept 6904 bearings.

This is a **service part only**. Wheels or hubs are **not included**. Compatible with DT Swiss hubs that require a 20 mm inner diameter *bearing.*

Compatibility & Technical Notes

  • Fits DT Swiss hubs designed for **6904 bearings** (e.g., certain DT Swiss 240 / 350 level rear and non-driveside positions)

  • 37 mm outer diameter — installed into hub shell or freehub body bore sized for 37 mm OD

  • Platform Type: Universal (hub repair bearing)

Service / Ownership Context

These bearings are press-fit into DT Swiss hub shells and freehub bodies. Proper bearing removal and installation tools are required (hub press or arbor press). Improper installation risks bearing damage or premature wear. Bearings typically fail from water ingress, grit contamination, or long service intervals.

Fit & Use Signals

  • Good Fit: You have a DT Swiss hub that specifically calls for a 6904 bearing (20×37×9 mm).
  • Good Fit: You are replacing worn or rough hub bearings.
  • Not A Fit: Your hub uses a different bearing size (e.g., 6902, 6803, 6802, 6805).
  • Not A Fit: You expect this to replace sealed cartridge bearings on non-DT Swiss hubs.
  • Not A Fit: You are expecting a complete wheel, hub, or bearing kit — this is a **single bearing**.
DT Swiss bearings like these are pressed into the hub shell or freehub body. You’ll usually find 6904 on certain non-driveside or rear hub bearings in hubs like 240s/350s — but not every position uses the same spec. Always measure old bearings or check DT Swiss spec before you buy. Buyers often assume one bearing size fits all DT Swiss hubs — it doesn’t. 20×37×9 is unmistakable once measured. If you replace just one bearing and others are rough, replace them all at the same time. Install with a proper press, not a hammer and punch — that’s how you damage seals and races. Expect decent longevity unless you ride in wet/muddy conditions — contamination kills bearings faster than anything. This SKU = individual bearing. For a hub you may need 2–4 depending on model and position. Check the wheel’s service manual for exact bearing count and locations.
