The TS-25 is comprised of a bracket that attaches to the top of the repair stand and holds your wheel securely in place, combined with a truing gauge with quick-release clamp that slides up and down to accommodate varying wheel sizes. The truing gauge slides out to the rim, so you can adjust it to true different rim widths and profiles.
