  • Sealed cartridge bearing
  • Chrome steel construction with a sealed cartridge for weather resistance

Fit by measurement

Headset bearings are sold by size, not by frame brand — measure the old bearing's inside diameter, outside diameter and width (or the stack height it sits in) and match it to 39.7x50.8x7.14mm before ordering.

Compatibility & fit

Confirm your headset's exact standard (e.g. ZS/EC/IS, 1-1/8 in or 1.5 in, straight or tapered) against this bearing's size before fitting — SCV does not publish a frame-model fitment list for this size, and the S.H.I.S. code isn't confirmed for this SKU.

Black Bearing covers manufacturing defects on its bearings for the period stated by the distributor at the time of purchase; wear from normal use, incorrect fitment or contamination is not covered. For warranty support, return the product to Tune Cycles and we'll manage the claim with Black Bearing's Australian distributor.
