Chris King DropSet 5 Headset (Matte Black) (1-1/8") (42/52mm) (45 Deg)

The Dropset 5 integrated headset features the patented GripLock bearing cap, which preloads the headset independently of clamping onto the steerer, so it retains preload far better than the competition and is impervious to the ill effects of load spikes from large hits and heavy braking. This means smoother steering, no more creaking, and a longer lasting headset.
