Knowing what your bike weighs shouldn't require a trip to the local post office or balancing your frame on a bathroom scale. The Park Tool DS-1 Digital Scale hangs from any sturdy hook or beam and lets you weigh complete bikes, frames, wheels, or components up to 25 kilograms with accuracy to within 20 grams. That's precise enough to settle debates about claimed weights versus actual weights, track the gram penalty of different build choices, or verify that your new carbon wheels actually hit their advertised numbers.

The scale uses a simple hook-and-strap system that works with frames, wheels, and complete bikes.

The backlit LCD shows weight in kilograms, pounds, or pounds and ounces depending on your preference. A tare function zeros out the strap weight or lets you weigh items in a bag or box without including the container. The auto-off feature preserves battery life when you forget to shut it down after weighing your latest upgrade.
