Park Tool TS-2Di Dial Indicator Gauge Set - Precision Wheel Truing Measurement Tool

The Park Tool TS-2Di Dial Indicator Gauge Set allows mechanics to true wheels to a level of precision beyond what the naked eye can ever see. Mounting directly to most Park Tool Professional Truing Stands, the TS-2Di provides exact numerical measurement of a rim’s lateral and radial runout, transforming wheel truing from a visual estimation process into a precise, measurable, and repeatable procedure. Each indicator in the set features a specially designed non-marring tip that rides smoothly along the sidewall or outer edge of the rim, measuring deviations as small as 0.01mm and displaying the measurement instantly on easy-to-read analog gauges. This level of precision is particularly valuable when truing high-performance carbon wheels, building competition-grade wheelsets, or diagnosing subtle rim damage that would be difficult to detect by eye alone. A standout feature of the TS-2Di is its adjustable range markers, which allow the mechanic to set a defined tolerance range and visually track exactly how close the wheel is to true perfection as adjustments are made. This makes the truing process faster and more confidence-inspiring, especially for less experienced mechanics still developing a feel for spoke tension and rim movement. The TS-2Di is compatible with the Park Tool TS-2, TS-2.2, TS-2.2P, TS-2.3, TS-4, TS-4.2, and TS-4.3 Professional Truing Stands, and includes all mounting hardware needed for installation. Note that on the TS-4, TS-4.2, and TS-4.3 truing stands, the TS-2Di cannot be used at the same time as the standard caliper fingers. KEY FEATURES Measures rim lateral and radial runout to a precision of 0.01mm. Non-marring tips protect rim sidewalls and outer edges during measurement. Adjustable range markers for visual tolerance tracking. Mounts directly to most Park Tool Professional Truing Stands. Compatible with TS-2, TS-2.2, TS-2.2P, TS-2.3, TS-4, TS-4.2, and TS-4.3. All mounting hardware included. Cannot be used simultaneously with caliper fingers on TS-4, TS-4.2, or TS-4.3.
