Chris King started making headsets in 1976 & have been refining them ever since. This model features a robust aluminium construction, which makes it more than ready to handle all the intensity that comes with long days on your bike. Whether you're clocking up the miles with your local road club or shredding the MTB trails, this versatile headset is engineered for maximum strength & performance. Built for precision, it sets the standard for quality by offering an integrated headset design that's built on the same pedigree of the brand's headsets from the past 40 years. Coming complete with a patented Grip Lock retention design, this model offers exclusively reliable headset adjustment. Technologies: Grip Lock: The most significant challenge to overcome is that integrated bearings are not pressed into a cup & sit loosely in the frame. When bearings are not pressed securely into a cup they shift & move, rapidly losing preload. As preload drops, the bearings are more susceptible to creaking, damage, & failure. Chris King's patented Grip Lock™ bearing cap is tried & tested & is a patented design that preloads the headset independently of clamping onto the steerer. The Grip Lock™ design ensures that the Chris King Drop Set™ 4 retains preload far better than the competition & is impervious to the ill effects of load spikes from large hits & heavy braking. This means smoother steering, no more creaking, & a longer-lasting headset.
