The DT Swiss HX 491 is a tough, welded aluminium rim built for the extra loads and torque of e-MTB riding, giving you a dependable foundation for heavy-duty trail and bikepacking wheels.

Highlights

  • 27.5 inch (650B) diameter, drilled 32 holes
  • 25 mm internal width suited to mid-volume MTB tyres
  • Welded rim joint for a smooth, consistent tyre bed
  • Tubeless ready with a hooked bead
  • Approved for e-MTB use, 150 kg maximum system weight

Built for e-MTB

The HX 491 is approved for e-MTB use and carries a 150 kg maximum system weight, so it handles the higher forces an electric drivetrain puts through the wheel. The welded joint and 21 mm depth give a strong, predictable rim that stays true through hard trail miles.

Compatibility & fit

This is a disc-specific rim with no brake track, so it suits disc-brake wheels only. The 25 mm internal width pairs well with mid-volume MTB tyres. It uses non-eyelet PHR spoke seats and a Presta valve hole, and is tubeless ready once set up with tape and a valve.

DT Swiss covers this rim with a 24-month warranty against material and manufacturing defects from the date of purchase. Normal wear items, including tubeless tape, are not covered. The DT Swiss crash-replacement (Fair Share) programme applies to carbon rims only and does not apply to this aluminium rim.

For any warranty support, please return the item to Tune Cycles and our team will handle the claim on your behalf.
