Chris King's Devolution headset solves a serious problem: How to match up your parts when parts standards keep multiplying? The Devolution lets you match frames and forks that would be otherwise incompatible. Got a 1-1/4-inch frame and a 1-1/8-inch fork? King has a headset that will make that combo work. How about an older 1-inch threadless fork and a shiny new 1-1/8-inch frame? That's a possibility, too. No shims, no special adapters, just the parts you need to make sure all your bike parts play nice.

Shim spacers can be placed between bearing and compression cover in IS headsets to fine tune the fitment.
