DUB Self-Extracting Cap Tool

What Our Gearhead Experts Are Saying:

"I’ve seen too many DUB caps ruined by makeshift tools. This one fully engages all four holes and stays put under load. The vise-friendly hex is a nice touch when extra leverage is needed, and the thread direction marking avoids costly mistakes."

Servicing modern crank systems occasionally requires removing components that were never meant for frequent adjustment. The DUB Self-Extracting Cap Tool is purpose-built for those rare but critical moments, providing mechanics with a stable and repeatable interface for SRAM DUB crank arm dust caps. The tool uses a four-pin interface that contacts all available engagement points on the dust cap, minimizing cam-out and uneven loading. A standard 3/8 square drive ensures compatibility with torque wrenches and ratchets commonly found in professional and home workshops. The external hex profile allows the tool to be clamped securely in a vise, enabling the crank arm to act as a lever for added mechanical advantage. Clear markings indicate the left-hand thread used by DUB dust caps, reducing the risk of incorrect removal direction.
