Description

Cane Creek's workhorse headset! The Forty Series is a quality product at a mid-range price point.

All of the Headset cups are machined from 6061 T-6 Alloy and utilise black-oxide sealed bearings. The crown races are made from treated steel and feature a single, low friction sealing lip to keep debris out. All of the parts from the Forty series headsets are cross-compatible with Cane Creek's 10 and 110 series headsets.

    Second time I have used this to convert a 42mm straight headset to tapered and has worked a treat as before. Great product.

    Cane creek ec40/44

    Replaced my 11/8 straight steerer shock with a 1 1/8 - 1.5 tapered steerer shock and so needed to swap out the bottom bearing with this external cup bearing , couldnt be happier with the result
