Works with our MASH AC Framesets!

Designed specifically for bicycles, Chris King made-in-house bearings are built to last a lifetime, fully serviceable, and backed by our ten-year built-to-last warranty.

Now, after making the very best pressed-in headsets for over 40 years, Chris King is releasing the DropSet™ 1, the first Chris King integrated headset. This project started from the ground up, beginning with testing to analyze the forces at play in an integrated vs a pressed-in headset design, and discovering the unique problems that needed to be addressed.

The most significant challenge to overcome is that integrated bearings are not pressed into a cup and sit loosely in the frame. When bearings are not pressed securely into a cup they shift and move, rapidly losing preload. As preload drops, the bearings are more susceptible to creaking, damage, and failure.
