Pedros Shop Chain Tool 1.2

A workshop chain tool with a bearing-mounted S2 steel pin, replaceable bridge and guide-pin shear slot, designed for repeat maintenance rather than disposal when a working part wears.

A spare pin is stored in the handle. Chain compatibility must follow the exact model's chart and the chain manufacturer's joining procedure; no claim of compatibility with all future chains is included.

Chain compatibility

• The March 2025 chart lists SRAM 12-speed Road/Transmission and 13-speed Transmission Flattop fit.
• A chain-fitting entry does not provide the Campagnolo peening operation. The starred Campagnolo entries permit breaking the chain but require a suitable separate tool for final master-pin peening.
• The 3/16-inch internal-width single-speed entry may require repositioning the bridge.
