Handlebars love to swing around while you're trying to work on the rest of the bike. Whether you're adjusting headset preload, wrapping bar tape, or installing brake levers, having the bars spin freely turns a simple job into a wrestling match. The Park Tool HBH-3 clamps onto your workstand and holds the handlebar steady, giving you both hands free to actually do the work instead of chasing a rotating cockpit.

The HBH-3 uses a cam-action clamp that locks onto bars ranging from 22.2mm to 31.8mm in diameter—covering everything from flat bars and risers to road drops and aero shapes.

The mount attaches to any standard workstand tube between 25mm and 38mm, which covers Park Tool stands and most other major brands.

Installation takes seconds: slide the mount onto your stand's upright tube, tighten the clamp, and position the holder where you need it.
