CHRIS KING HEADSETS
With all of the steerer/headset standards you see in the bike industry these days, it's quite possible that you'll need a whole new headset if you buy a new bike or fork. But if you're lucky, you'll be able to swap your trusty Chris King Headset to the new model. Perhaps you've been running a 1.5 bottom cup with the DEVO reducer base plate, but your new fork is a 1.5 taper. You'll need this Chris King 1.5 Standard Base Plate. It mates a 1.5" steerer to a 1.5" lower NoThreadset cup.
