Cane Creek 40-Series Zero Stack Tapered Headset.

The 40Series is the workhorse of Cane Creeks headset lineup. The series incorporates all the features necessary for a durable, lightweight, longlasting headset and represents the perfect balance of performance, durability and value. Suitable for any type of bike including road, gravel MTB. The new ZN40 bearings are a zinccoated, machined steel cartridge bearing with hardened steel balls. The new material is much more corrosionresistant, which vastly increases the longevity of the 40 series headsets.
