A Cane Creek 40-Series lower headset bearing built as a custom drop-fit for Cervelo frames, sized S.H.I.S. IS49.

Compatibility & fit

1-3/8in integrated bottom bearing, 36°/45° contact angle, zinc-plated, for a 49.1–49.2mm head tube bore. Cane Creek built this specifically to fit Cervelo frames — check your frame model before ordering, since IS49 is not a size shared with other brands.

Cane Creek covers this spare part under its Small Parts warranty: 1 year against defects in materials and workmanship. For warranty support, return the product to Tune Cycles and we'll manage the claim with Cane Creek's Australian distributor. This is in addition to your rights under the Australian Consumer Law, so keep your proof of purchase.
