Truing a bicycle wheel with bladed aero spokes can be precarious — one careless adjustment can twist or bind the spoke, weakening the spoke and defeating the purpose of the aero design. The BSH-4 securely holds bladed spokes in place, preventing twisting and making tension adjustments easier. Features a lightweight ergonomic design and four different sized slots to fit a wide variety of bladed spokes.

• Fits bladed spokes from 0.8 mm to 2.0 mm width
