Axle clamps and lower legs are machined to hold the axle without distorting the fork. Inner tubes carry a low-friction coating; once it is through, the seals wear quickly. Öhlins publishes tube diameters by fork model, and they are not interchangeable across the range.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins publishes dimensions for its service parts so a workshop can verify before it fits. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eOrder under 21630-05. Where several sizes share a description, only the number separates them. The published dimensions are dimension a 43 mm, dimension b 50 mm, dimension c 55 mm — measure the old part against them if you are unsure. Fork tubes are the structural part of the front end and carry the braking load into the yokes. Outer tubes hold the bushings and the seal head, so their bore finish matters as much as the inner tube's outside.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\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 21630-05\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Fork Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 43 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 55 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":53650670027018,"sku":"21630-05","price":7982.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21630-05_33ce84ba-5917-406f-b88d-76544081818f.png?v=1788877317","url":"https:\/\/inter-pace.com\/en-tw\/products\/ohlins-fork-leg-outer-43-50-55-508-21630-05","provider":"Inter-Pace","version":"1.0","type":"link"}
