Chris King DropSet 2 Headset

The Chris King DropSet 2 Tapered Headset with IS42 upper cup and IS52 lower cup for frames with a 42 mm bearing seat at the top and 52 mm at the bottom of the head tube, and forks with a tapered steerer tube diameter of 1 1/8 inch / 28.6 mm at the top and 1.5 inches / 40 mm at the bottom.

Please note that the integrated bearing housing requires different bearing angles depending on the frame manufacturer. The DropSet 2 has a bearing angle of 45x45 degrees at the top and 45x45 degrees at the bottom, and the top bearing has an installation depth of 2.8–3.0 mm. If in doubt, please check with the frame manufacturer to ensure this headset is compatible with your frame.

The headset has been developed for heavy-duty cycling and also performs well on road bikes. The cap covers are made from aluminium and CNC-machined; the bearings are made from stainless steel, feature multiple seals and are so well-made that Chris King offers a 10-year warranty on all headsets. Furthermore, the bearings are easy to maintain.

Chris King quality:

Anyone who hears the name Chris King immediately thinks of extremely durable headsets. Manufactured by Chris King in Portland, Oregon, USA, to a standard of quality that rightly deserves the label ‘indestructible’. The benchmark in headsets – often copied, never equalled – which is why there is a 10-year warranty.
