DUB Self Extracting Cap Tool

Abbey Bike Tools DUB Self Extracting Cap Tool is the kind of precision-engineered shop essential that makes crank service faster, cleaner, and more reliable. Designed specifically for SRAM DUB crank arm dust caps, this tool engages all four holes for a secure, no-slip fit—because rounding out a cap is never part of the plan.

Built with a standard 3/8" square drive for use with common shop tools, it also features a hexagonal exterior that can be clamped in a vise, letting you use the crank arm itself as leverage when needed. The left-hand thread marking keeps orientation clear, avoiding frustrating mistakes during reassembly.
