Machined in the USA from aluminum, it mounts to the seat tube and holds your chain in place without the bulk of a full bash guard setup. Paul Component Engineering has been making hardware like this for decades — tight tolerances, clean aesthetics, zero compromise on material quality.\u003c\/p\u003e\n\u003cp\u003eThe Chain Keeper is designed for single-chainring drivetrains where chain retention matters and extra weight doesn't. Whether you're running a 1x setup on a gravel bike or keeping a dedicated single-speed tidy, this is the kind of component that installs once and stops being something you think about.\u003c\/p\u003e\n\u003ch3\u003ePaul Component Engineering Chain Keeper Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Tube Diameter:\u003c\/strong\u003e\u003cspan\u003e 28.6mm, 31.8mm, \u003c\/span\u003e35.0mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ePaul Component Engineering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eMachined aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended Use:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSingle-chainring chain retention\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUSA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Paul","offers":[{"title":"Black \/ 28.6mm","offer_id":45449732194348,"sku":"600","price":107.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ 31.8mm","offer_id":45449732227116,"sku":"610","price":107.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ 35.0mm","offer_id":45449732161580,"sku":"620","price":107.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/PAUL-COMPONENTS-CHAIN-KEEPER-BLACK-1_a4cafc36-36e2-404d-9224-287742d263c8.jpg?v=1776103097","url":"https:\/\/racycles.com\/pt\/products\/paul-component-engineering-chain-keeper","provider":"RA Cycles","version":"1.0","type":"link"}
