Chris King InSet 5 Headset ZS49

Chris King InSet 5 Headset Bearing - 49 mm straight headtube for a 1 1/8" to 1.5" tapered steerer tube.

CK created the InSet family of headsets by applying the legendary form and function of Chris King headsets to fit solutions for a wide variety of tapered and oversized headtubes and steerer tubes being utilized in modern bicycle design.

The InSet is built for riders that need the precision adjustment and legendary performance of a Chris King headset on bikes that have headtubes designed for a zero stack (ZS), or mixed zero stack (ZS)/external cup (EC) headset. For frames with internal bearing cups that are pressed into the head tube.

Why CK made this:

Contemporary bicycle frame designs are incorporating larger diameter headtubes and tapered-steerer forks to improve the bike's front end stiffness, and as a result handling accuracy. This move has made particular sense for off-road bikes. This is the evolved form and function of the legendary NoThreadSet to address the variety of tapered steerers and headtubes on the market today.

Why you want it:

Every Chris King headset is built with heat-treated bearings, and surgical-grade steel races 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 upon years of demanding riding.

Features:

• Headset type: Zero Stack (ZS) or mixed Zero Stack/External cup (EC)
• Legendary made-in-house bearings
• Patented GripLock® retention design for dependable headset adjustment
• Designed specifically for a 49 mm straight headtube and a 1 1/8" to 1.5" tapered steerer tube
