Chris King DropSet 4 headset

The Chris King DropSet 4 headset with IS42 upper cup and IS42 lower cup for frames with a 42 mm bearing seat at the top and 42 mm at the bottom of the head tube, and forks with a steerer tube diameter of 1 1/8 inches / 28.6 mm at the top and 1 1/8 inches / 30 mm at the bottom.

Please note that the integrated bearing housing requires different bearing angles depending on the frame manufacturer. The DropSet 4 has a bearing angle of 45x45 degrees at the top and 36x45 degrees at the bottom. 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 made from stainless steel with 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.

Chris King GripLock:

The NoThreadSet headset with the newly developed GripLock cap. The multi-piece cap is fitted with a slotted cone ring, which allows for an even easier connection between the steerer tube and the head tube

Head sets with 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.
