A single replacement headset bearing sized for a 1-1/2in lower (S.H.I.S. IS52), built with a 45°/45° contact angle for frames using 45-degree crown races.

Compatibility & fit

52.0mm bearing, 45°/45° contact angle, zinc-plated. Fits 45-degree crown races only — it is not interchangeable with the standard 36°/45° IS52 bearing, so check your headset's contact angle before ordering.
