Chris King Dropsets bring you that legendary build quality and durability for your integrated headset bike frame. The Chris King DropSet 5 IS42/IS52/45 Headset has their GripLock™ bearing cap, which preloads the headset independently of clamping onto the steerer, so it retains preload far better than the competition. That means a creak-free ride experience, along with King's inherent cool factor.
Anodized Aluminum
Legendary Made-In-House Bearings – These heat-treated bearings have surgical-grade steel races that are machined simultaneously to ensure they are perfectly matched. As Chris King bearing tracks age and burnish, they actually get smoother, and all headsets are fully serviceable for years of demanding riding.

Engineered, Manufactured, and Assembled in Portland, Oregon
