Service / Ownership Context
These bearings are pressed into the hub shell on both sides of the hub. Proper bearing tools (hub press or arbor press) are required for service. Bearings fail from contamination or long service intervals — replacing both sides at once is recommended for best performance.
Fit & Use Signals
- Good Fit: Your DT Swiss front hub calls for a 17×28×7mm bearing.
- Good Fit: You’re servicing a DT Swiss 240 EXP mountain front hub.
- Not A Fit: Your hub uses different bearing sizes.
- Not A Fit: You expect this to be a wheel or hub — this is a **single bearing**.
- Not A Fit: You want a full bearing kit.
DT Swiss uses specific bearing sizes in different hub locations. The 1728 (17×28×7) is often found in 240 EXP mountain/front hubs — generally on both sides of the front hub. Always verify by measuring your old bearing before ordering. Buying just one can be fine, but if one side feels rough, both sides are usually worn similarly. Press-in and press-out require proper tools. Hammers and punches ruin seals. This SKU = single bearing. For a front hub, you’ll typically need two per wheel (left and right). Always ask a tech or check spec sheet to verify exact count and orientation. Common mistake: mixing this with 6900 series bearings. They differ in ID and OD — mismatching will not press in. Install with correct driver that only contacts the outer race. Never hammer on inner race — that destroys bearings immediately.
