About Chris King
Q & A

Taking the headache out of combining an old fork with a new frame, or vice versa. The Devolution 1.5 takes advantage of the modular design used in all Chris King headsets, allowing a 1.5" headtube to accept a fork with a 1 1/8" steerer using a custom baseplate and bearing cap. 

Sharing the same 7075 aluminium cup design as the 1.5" NoThreadSet, the Devolution uses proprietary high precision stainless steel cartridge bearings featuring 32 rolling elements in each cup which spread load over 64 points of contact for a silky smooth feel. And of course it features the Chris King 10 year guarantee

The patented design allows King headsets to be user serviced with little more than a pen knife and some high quality grease. Whilst the modular construction and wide availability of replacement components ensure it will outlast any number of frame and fork combinations, and can even be converted to a standard 1.5 NoThreadSet if required.

Steerer Size: 1 1/8"
Steerer Tube Size:  1.5"
Total Stack Height: 37.3mm
Weight: 250g

Note: Threadless headsets require the use of specialist tools for fitment. Tweeks Cycles recommend the headset is fitted by a qualified mechanic using Chris King's headset press adaptor (available separately)
