Park Tool wheel truing stand SG-7.2, grey, single unit (PTSG72)

Park Tool wheel truing stand SG-7.2 in grey finish is a single-unit workshop tool designed to support accurate bicycle wheel alignment and rim straightening. The stand provides a stable platform to inspect lateral and radial runout and to hold wheels securely while making spoke adjustments. The hardened steel construction and molded contact points protect the wheel rim and hub during use, and the dual cutting slots accept standard and carbon blade widths for controlled trimming of aero-shaped seat masts, seat posts and round tubes within the compatible diameter range.

Advantages

The truing stand offers a rigid, low-deflection frame that minimizes vibration and movement while you true wheels. Molded contact points reduce the risk of damaging rims or hubs, while the two cutting slots — standard and carbon — allow safer, more precise sawing of aero-type seat masts, seat posts and steerer tubes. Its compact single-unit design makes it convenient for workshop benches and mobile repair setups.

Suitable for

• Inspecting and correcting lateral and radial wheel runout
• Routine wheel maintenance and repair in bike workshops
• Holding wheels securely for spoke tension adjustments
• Trimming aero-shaped seat masts, seat posts and round tubes within the supported diameter range

Key specifications

• Material: hardened steel body with molded contact points for protection
• Finish: grey
• Cutting slots: two widths — standard and carbon blade compatible
• Compatible tube diameters for cutting guidance: 22 mm to 45 mm (7/8" to 1-3/4")
• Maximum seat mast/seat post trimming diameter: up to 70 mm (2.75")
• Configuration: single-unit truing stand suitable for bench use

How to use

Mount the wheel securely in the stand according to the wheel axle and hub type so the rim sits between the adjustable guides. Rotate the wheel slowly and use the adjustable feeler or gauge points to identify lateral and radial deviations. Make spoke adjustments incrementally, rechecking the rim position frequently until runout is within acceptable limits. For trimming aero-shaped seat masts, seat posts or round tubes, place the tube in the appropriate cutting slot (standard or carbon width) and use a fine-toothed hacksaw guided by the slot for a straight, controlled cut. Ensure the molded contact points are positioned to avoid scratching the tube or surrounding surfaces.

Usage recommendations

Use calibrated spoke wrenches and a rim-tape or protector when truing to avoid damage. When cutting composite or carbon parts, use the carbon-width slot and a blade suitable for composites; wear eye protection and follow manufacturer guidance for carbon component cutting. After trimming, deburr cut edges and check fit before reassembly.
