Dynamic Double Checker chain gauge
In one tool, you get a chain checker for 7–13 speeds (including SRAM Flattop) and at the same time a rotor thickness gauge. Thanks to the precise 3-pin construction, it measures the actual wear of the chain pins, not the "rollers" like common gauges, making the result more reliable. The rotor check works with precise slots for minimum thickness and is compatible with most major brands (Shimano, SRAM, Campagnolo, Magura). It also includes a hook to stabilize the chain during measurement and an integrated ruler for quick dimension checks. The body is laser-cut from anodized purple aluminum, and you'll find a wear-guide directly on the tool, so you don't need a manual.
