nice tool but not necessary
- Familiarity: I've used it several times
You buy this tool and after a while you realize that a chain life is about 2500 miles. Forget the tool and stick to a 2500 mile chain replacement schedule and save $30.
Cheaper than a new cassette
If you've ever made the mistake of running your chain too long, and needing to replace your cassette as a result, then spending less than $30 on a chain checker is money well spent. Just need to remember to check your your chain regularly.
Checked a new chain against an old one with this.
Dead on accurate. A bit OCD to own but worth it.
