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.
