Product review
Construction and materials: The pliers are manufactured from high-quality, heat-treated steel for long life and resistance to bending or wear. The jaw faces are hardened to secure master links without slipping or deforming the chain plates.
What’s included: One 2-in-1 master link plier designed to both open and close quick links. The tool ships ready to use with the return spring and clasp fitted.
Design and ergonomics: Cushioned, non-slip handles provide a comfortable grip and improved control when your hands are oily or wet. The tool incorporates a return spring so the jaws reopen automatically between actions and a safety pin that limits over-extension of the tips.
Compatibility and sizes: Made to work with a wide range of modern bicycle chains, it is compatible with major manufacturers such as SRAM, KMC, Shimano and others. It handles common multi-speed widths, including 9-, 10-, 11- and 12-speed chains, and suits most master-link designs.
How to use: Position the jaw tips on the quick-link tabs, squeeze the handles to separate the link, and reverse the action to rejoin a master link. The tool’s leverage and jaw geometry let you open and close links cleanly without hammering or improvised methods. When not in use, fold and secure the handle clasp to reduce its footprint for storage.
Pros
- Durable hardened-steel construction
- Dual-function for opening and closing links
- Spring action and handle latch for quick use and storage
Cons
- Safety pin or spring may need occasional adjustment
- Not intended for heavy industrial use
- Handles can feel tight for large hands
VerdictA rugged, no-frills chain tool that removes and reconnects master links with reliable grip and smooth leverage. The hardened-steel jaws and spring-loaded action make it easy to operate even with greasy hands, and the safety pin prevents over-opening. It’s compact enough to tuck into a home toolbox or a saddle bag and handles the common multi-speed chain widths used on modern bikes. A practical cho

Good full-size pliers for e-MTB
I originally bought a tiny travel version, but this full-size plier complements my e-MTB toolkit. Solid, easy to handle, and highly recommended.

Good choice for casual mechanics

Very good — recommended
Works very well. The spring can come out sometimes but it’s simple to snap back in. Soft grip covers feel comfortable. Suitable for both removing and fitting chains — recommended.
