A worn chain is slower, wears out the whole drivetrain and can break more easily; rotors that are too thin drastically reduce braking power compared with new ones.\u003c\/p\u003e\u003ch3\u003eMeasures real pin wear and rotor thickness\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003ethree-point design\u003c\/strong\u003e measures real pin wear, the most relevant parameter, excluding the influence of roller wear that skews many traditional gauges. It works with 7- to 13-speed chains, including SRAM Flattop, Shimano and Campagnolo. The rotor slots are dedicated to SRAM, Shimano, Campagnolo, Magura and Hope rotors. It is made of anodised aluminium, with a chain hook and a ruler.\u003c\/p\u003e\u003ch3\u003eHow to read the measurements\u003c\/h3\u003e\u003cp\u003eFor the chain, insert points 1 and 2 with the pins facing down, lift the chain to put it under tension and press point 3. Below 0.5% the chain is in good condition; at 0.5% 11-, 12- and 13-speed chains need replacing, at 0.75% 7- to 10-speed chains. If the rotor fits into its brand's slot, it needs replacing.\u003c\/p\u003e\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eChain measurement\u003c\/strong\u003e: real pin wear, three-point design.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eChains\u003c\/strong\u003e: 7- to 13-speed, SRAM Flattop included.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eThresholds\u003c\/strong\u003e: 0.5% and 0.75% depending on speeds.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eRotors\u003c\/strong\u003e: slots for SRAM, Shimano, Campagnolo, Magura and Hope.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e: anodised aluminium.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eChain hook\u003c\/strong\u003e: for opening and closing the quick link.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eRuler\u003c\/strong\u003e: integrated.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eInstructions\u003c\/strong\u003e: printed directly on the tool.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\u003ch4\u003eWhy exclude roller wear?\u003c\/h4\u003e\u003cp\u003eMany gauges rest on the rollers and add their play to the real elongation, flagging a chain for replacement too early.
