Face flatness matters as much as thickness — a shim that does not seal against its neighbour leaks damping. Shims are reused only if they are undamaged and flat; a coned shim is finished. Öhlins grinds shims to a flatness tolerance because the faces have to seal against each other.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eBuying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Where a number has been superseded, Öhlins states the replacement — we pass that on. Order by part number. The dimensions below are the ones Öhlins publishes for it.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003ePart number 00525-20 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. inner diameter 12 mm, outer diameter 20 mm, thickness 0.25 mm is what distinguishes this number from its neighbours in the range. Shim thickness is measured in hundredths of a millimetre because that is the resolution at which damping force changes. Changing one shim in a stack alters the damping curve measurably; that is why Öhlins sells them individually rather than only as sets.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBrand:\u003c\/em\u003e Öhlins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart Number:\u003c\/em\u003e 00525-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Shims\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThickness:\u003c\/em\u003e 0.25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCountry of Origin:\u003c\/em\u003e Sweden\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53648829022474,"sku":"00525-20","price":1.76,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00525-20_2e7f85a7-0bd0-40d5-8a9a-e25c9bcd41e1.png?v=1788872082","url":"https:\/\/inter-pace.com\/en-za\/products\/ohlins-shims-12-20-0-25-00525-20","provider":"Inter-Pace","version":"1.0","type":"link"}
