Park's TS-2.2 Professional Truing Stand has been a staple in bike shops for decades because it's so reliable and easy to use. It accepts all common wheel diameters up to 29 inches with and without tires. It's made of heavy chrome-plated steel with nylon bushings at pivot points and can be bench-mounted, vise-held or attached to Park's Tilting Base (sold separately). The best feature is that this stand automatically centers rims over the hubs, which saves time repairing and building wheels. Also, installing the wheel and positioning the caliper for truing is quick and easy thanks to the stand's separate knobs for each setting. This is an awesome truing stand that will last a lifetime.
