ASSEMBLY
The Park Tool TS-2 Truing Stand is shipped from the factory adjusted and ready for use.
The only assembly necessary is to thread the caliper arm adjusting knob and shaft unit
into the threaded bushing on the front of the base. A thin layer of grease on the threads
will assure smooth operation. The stand may be clamped or bolted to a workbench or
clamped in a vise for stability during use. An optional tilting base accessory (TSB-2) is
available which allows tilting the stand forward and back for more comfortable use at any
bench height.
If treated with care, this Park Tool TS-2 Truing Stand will last for generations. A
minimum amount of maintenance and care is required to keep your stand accurate.
SET UP
Remove the tire, tube, and rim strip from the wheel to be trued. Remove the quick release skewer or axle
nuts and washers from the axle. Rotate the axle to make sure it is not bent and to check for proper cone
adjustment. All spacers and locknuts MUST be in place and properly adjusted on the axle before placing the
wheel in the truing stand.
Turn the caliper arm knob (Ref. #17) in several turns until the caliper arm is low enough to clear the rim.
Turn the caliper adjusting knob (Ref. #21) in several turns until the calipers spread far enough apart to clear
the width of the rim.
Turn the upright adjustment knob (Ref. #9) counter-clockwise until the uprights are far enough apart to permit
the axle to be placed in the “V” shaped notches in the uprights. Turn the knob clockwise until the uprights just
TOUCH the locknuts on the axle. This will center the rim on the hub and automatically provide the proper
“dish” or offset for the freewheel. It is NOT necessary to “clamp” the hub between the uprights by
overtightening the knob. Excessive force on the knob may cause the uprights to flex slightly, making the
dishing inaccurate.
Adjust the caliper and caliper arm knobs (Ref. #21 and #17) until the calipers clear the rim by about 1/8 inch.
Rotate the wheel. If the rim hits the calipers at any point in the rotation, adjust the knobs to increase
clearance. Begin adjusting spokes to true the wheel. As the wheel becomes more true, move the calipers
closer to the rim until the tips of the calipers almost touch the rim.
WHEEL TRUING BASICS
Relax and work slowly and patiently at first. Do not rush the process. Speed will come with experience. Consult
an experienced bicycle mechanic if you encounter an unexpected problem or if your efforts are not improving the
condition of the wheel.
Thoroughly inspect the wheel and its components before starting the truing process. Remove the tire, tube, and
rim strip from the rim and inspect the tire for bits of glass or thorns, and for cuts, tears, scrapes, and worn spots in
the tread and sidewall. Inspect the rim for cracks and/or bulges around the holes, as well as for dents and flat
spots in the rim’s sidewall. Squeeze parallel pairs of spokes, checking for any that are broken, brittle, or loose.
Check for spoke nipples that may be rounded, rusted, or corroded. Make sure there are no cracks in the shell of
the hub and that the hub is properly adjusted and the axle is not bent. Repair or replace parts as needed.
