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.
- Item #UNR000H

decent tool to pound on the crown races. It's heavy and solid and will most likely outlast any bike I build

Right tool for the job.
- I've used it once or twice and have initial impressions
Sturdy crown race setter that will stand the test of time. I like that it comes with adapters for different diameter races. My only complaint is it's a little short so I had to lop off a bit of steerer on a new fork before the setter could drive the race home.

A nice, proper tool for the job
- I've used it several times
This tool makes quick work of installing headset races. The construction quality is great and you'll be much happier using it versus any other technique for the job.
