Unior Master Bike Chain Tool for 6 to 13-Speed, AXS and Campagnolo Chains

Unior Master Bike Chain Tool for 6 to 13-Speed, AXS and Campagnolo Chains

• EXTENSIVE CHAIN COVERAGE: Compatible with standard 6- through 13-speed derailleur chains, SRAM AXS flat-top chains and most 1/8-inch single-speed chains. It also supports peening Campagnolo 11-, 12- and 13-speed connecting rivets using the included pin-blocking component.
• FLOATING CHAIN SUPPORT: The self-aligning floating support squares the chain plate with the driving pin before pressure is applied. This alignment helps the pin advance cleanly through the rivet while reducing the risk of an off-center push, damaged outer plate or poorly positioned connecting pin.
• THREE INTERCHANGEABLE INSERTS: Includes a standard single-link support, a wider double-link support for increased stability and a dedicated insert shaped for SRAM AXS flat-top chains. Integrated magnets help position the removable supports correctly when changing configurations.
• REPLACEABLE PIN STORAGE: A replacement driving pin is included and stored inside a concealed compartment within the tool body, keeping the spare protected and readily available. The replaceable pin is shared with the Unior Pro Chain Tool, simplifying spare-part management in professional workshops.
• PROFESSIONAL MACHINED BODY: The trivalent chrome-plated machined body measures 89.5 × 42 × 191.5mm and weighs 560g, providing a stable platform for frequent chain service. Its modular construction suits bicycle shops and mechanics working across modern road, gravel, mountain and single-speed drivetrains.
