It helps you check the distance between the center of the seat tube and the center of the chainring, with a reference for a 42 ± 2 mm chainline.\u003c\/p\u003e\n\u003cp\u003eThe machined contact surface helps keep the tool perpendicular to the seat tube. Align one of the markings with the center of the tube and check that the center of the chain falls between the two outer markings. The tool is intended for NJS geometry; other bottom bracket shell widths and rear hubs may require a different measuring method. Work carefully so that the edges do not scratch the frame.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQuick Specs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eModel: Runwell GAUGE42A\u003c\/li\u003e\n\u003cli\u003eType: Chainline gauge\u003c\/li\u003e\n\u003cli\u003eUse: Checking the chainline on NJS track bikes\u003c\/li\u003e\n\u003cli\u003eReference measurement: 42 ± 2 mm\u003c\/li\u003e\n\u003cli\u003eMaterial: Aluminum\u003c\/li\u003e\n\u003cli\u003eDimensions: 80 × Ø13 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 28 g\u003c\/li\u003e\n\u003cli\u003eFinish: Glass-bead blasted and anodized\u003c\/li\u003e\n\u003cli\u003eColor: Matte black\u003c\/li\u003e\n\u003cli\u003eDetail: Hole for a cord or ball chain\u003c\/li\u003e\n\u003cli\u003eCountry of manufacture: Japan\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Runwell","offers":[{"title":"Default Title","offer_id":59704048779589,"sku":"RW-170","price":14.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/7406\/6245\/files\/runwell-gauge42a-1.jpg?v=1791888631","url":"https:\/\/www.urbanbikewear.com\/en-global\/products\/runwell-gauge42a-chainline-gauge","provider":"urbanbikewear.com","version":"1.0","type":"link"}
