Diameter and length together identify the tube — both are specific to the damper it came from.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 21006-07\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eThis position is identified by its number rather than by a dimension. A scored bore means lost damping, because the oil bypasses the piston rather than being forced through the shims. Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load. Öhlins matches tube and piston as a pair during assembly, which is why the part numbers are specific.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. The exploded drawing for your unit names the number; if you do not have it, we do. The Öhlins exploded view names the number for each position; we can look it up if you do not have it.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e21006-07 is the Öhlins number for this position — the same one printed in the service documentation. Where no measurement is given, the drawing position is what identifies the part. Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load. Surface finish is specified in microns, because it decides how quickly the piston band wears.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eWe are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.\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 21006-07\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Tubes\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":53652459127050,"sku":"21006-07","price":58.17,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21006-07_a2034943-72e7-4c8e-bab2-b0d711675eee.png?v=1788879252","url":"https:\/\/inter-pace.com\/en-ie\/products\/ohlins-cylinder-tube-91-fe-21006-07","provider":"Inter-Pace","version":"1.0","type":"link"}
