Chris King GripNut 1-inch EC30 threaded headset

The GripNut headset brings the proven Chris King quality to classic older frames that feature a threaded steerer tube instead of the Ahead standard commonly used today.

Chris King GripNut 1-inch headset – specifications and dimensions:

• Material: CNC-machined aluminium, anodised
• Bearings: Industrial bearings, multi-sealed
• Top: EC 30/25.4 thread, 24 tpi for 1-inch steerer tube
• Bottom EC 30/26 for 1-inch taper/steerer tube
• Overall height: 37.4 mm, cup height 11 mm, GripNut height 12 mm
• Weight: 93 grams (manufacturer’s specification)
• The headset cannot be used with spacers or brake cable retainers

A clamping sleeve between the adjustment nut and lock nut secures the steerer tube rock-solid, even if its thread is damaged or it has been sawn off slightly too short. Due to this design, the GripNut headset is not suitable for bicycles with spacers or brake cable stops between the adjustment nut and lock nut.

The bearing cups and caps are made from aluminium and CNC-machined; the industrial bearings are multi-sealed and so well-finished that Chris King offers a 10-year warranty on all headsets.
