As a fundamental component of the headset, your bike's crown race simply must be installed properly — fail to do so, and you could destroy your frame, or worse, your entire headset assembly could loosen mid-ride and create a safety issue. To get the job done right, there's the Unior Crown Race Setting System. Interchangeable inserts make the tool usable for 1-, 1.125-, 1.25-, and 1.5-inch steerer tube races, and the fact that it's made of tempered, hardened, tool-grade steel means it'll even outlast your obsession with bikes.
