When to use Grade 25

Wheels Manufacturing recommends Grade 25 (or better) where both the cup and cone are machined; where they are not machined, its lower-cost Grade 300 balls are the recommended match.

Compatibility & fit

Fits many brands of loose-ball, cup-and-cone hubs, headsets and bottom brackets in 1/4" diameter; confirm your existing ball size before ordering. Tune's workshop can carry out the bearing service.

Wheels Manufacturing backs its loose ball bearings with a 12-month warranty against manufacturing defects, plus a 30-day return window (wheelsmfg.com).

For warranty support, return the product to Tune Cycles and we'll manage the claim with Wheels Manufacturing's Australian distributor.
