What Is the BSH-4 Bladed Spoke Holder Used For?

The Park Tool BSH-4 Bladed Spoke Holder is designed to prevent bladed or aero spokes from rotating while you tension or true a wheel. Bladed spokes can spin freely inside the hub flange, making it impossible to apply torque at the nipple without the spoke twisting and winding up. The BSH-4 clamps to the flat section of the blade and holds the spoke in a fixed position, giving your nipple driver something stable to work against so the tension goes exactly where it needs to go.

Wheelbuilding and truing with bladed spoke technology requires this tool. Without it, you'll fight the spoke on every turn of the nipple and end up with wound-up tension that releases unpredictably. The BSH-4 makes aero spoke work fast and accurate whether you're building from scratch or chasing a lateral deviation in an existing wheel.

FAQ

Why do bladed spokes need a spoke holder?

Bladed spokes rotate freely at the nipple interface. Without a holder, turning the nipple causes the spoke to wind up rather than applying clean tension.

What spoke blade widths does the BSH-4 accommodate?

The BSH-4 accommodates standard bladed spoke widths found on most aero road and gravel wheelsets. Verify compatibility with your specific spoke profile before use.

Can the BSH-4 be used for wheelbuilding as well as truing?

Yes. The BSH-4 is equally useful during wheelbuilding from scratch and when truing an existing bladed spoke wheel.

Best For

Wheelbuilders and mechanics working with bladed or aero spokes. An essential tool for anyone who builds or services aero wheels without struggling against spoke wind-up.
