What can be said about the NoThreadset. Probably a fair number of your riding buddies have them. They last nearly forever. Most of us have moved the same King headset from frame to frame. Winter after winter without ever taking the seals out to clean the bearings. When properly installed, going beyond the 10 year warranty is normal for a King Headset. The 1 1/8" threadless headset has been mountain bike standard for a few years now. Now many road bikes have adopted this size and style. It works great there too. This change has made for stronger, lighter road forks and frames. Chris King was one of the first manufacturers to offer a threadless headset. Each NoThreadSet includes our custom starnut and a matching stem cap. Total Stack height 31.4mm Lower Stack height 13.7mm Weight 98 grams fitting with our retail associate - Craig MacMartin Cycles/Glasgow Cycles based in Pollokshaws, Glasgow (see 'contact us' for further details) - for just £5 when purchased with this headset. This includes facing of the frame if required, and and installation of the headset by Cytech certified mechanics using professional tools. This service normally costs £15.
