Landing page captured for the 2026-09-08 issue.

Field notes

The page separates the tool into an on-bike Complete kit and a bench-oriented Basic kit. The Complete version includes a cylinder-pressurizing hose and stubby seal driver, while the Basic version omits both and is listed for work with the cylinder head removed. Both are marked in stock, with SKUs 1927-CK and 1927-BK, and the site states that qualifying orders ship the same day.
