Gusset Squire Single Speed Chain Tensioner – Anodised CNC Alloy Black

The Gusset Squire Single Speed Chain Tensioner is a high-performance solution for riders converting to single speed drivetrains. Designed to replace a traditional derailleur, it offers precise and adjustable chain tension across a wide range of bike setups—from rigid frames to full-suspension builds.

Crafted from CNC-machined alloy, the tensioner features a sealed bearing pulley for smooth, quiet operation and a steel no-jump guide cage to prevent chain drops. It comes with two springs, allowing you to choose either push-down or pull-up chain tensioning, depending on your bike’s geometry or preference.

Finished in a sleek black anodised coating, the Gusset Squire combines functionality with a clean, minimalist look—making it the ideal choice for MTB, dirt jump, and urban single-speed builds.
