Chris King DropSet 5 Ceramic Headset

The Chris King DropSet 5 Tapered headset with IS42 upper cup and IS52 lower cup for frames with a bearing seat of 42 mm 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 6.96 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 looks great on a road bike. The cap covers are made from aluminium and CNC-machined; the bearings are ceramic, multi-sealed and so well-made that Chris King offers a 10-year warranty on all headsets. Furthermore, the bearings are easy to maintain.

Chris King quality:

When you hear the name Chris King, you automatically think 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.

Chris King Ceramic Bearings

Chris King’s ceramic bearings offer the same qualities in terms of durability, maintenance and performance, but are even lighter and harder than the tried-and-tested stainless steel bearings. One of the most outstanding features of the ceramic balls used is their incredibly geometrically perfect roundness; furthermore, the extremely smooth surface guarantees optimal rolling behaviour and precision fit. The ceramic bearings are even lighter and harder than the stainless steel bearings; embedded in external bearing cups and multi-sealed, the bearings are virtually indestructible.

IS integrated Standard fully integrated headsets:

Head sets with the Integrated Standard (IS) require frames that incorporate the raceway for the head set bearings. Hence the name ‘fully integrated’. The head set then consists of the bearings inserted into the head tube of the frame, plus the fork cone and upper bearing cover with cap and claw.
