A bent inner tube is scrap — straightening changes the wall and it bends again. Inner tubes are coated because they run in bushings and seals for their whole life. Öhlins fork parts are specific to the fork model, not interchangeable across the range.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. The part number is the contract: it defines material, dimension and finish together. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. Öhlins parts are unit-specific: a close dimension is not a substitute.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21005-49 in the exploded view for the unit it belongs to. The published dimensions are dimension a 36 mm, dimension b 98.5 mm — measure the old part against them if you are unsure. Fork parts are specific to the fork, not to the motorcycle it happens to be fitted to. Axle clamps are machined so the axle clamps without pinching the fork out of alignment.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 21005-49\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Inner Tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 36 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 98.5 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":53652454932746,"sku":"21005-49","price":21000.0,"currency_code":"XOF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21005-49_04d9e957-64b8-4ba4-9ef1-c3e8d3518a00.png?v=1788879234","url":"https:\/\/inter-pace.com\/en-ci\/products\/ohlins-inner-tube-36-98-5-al-21005-49","provider":"Inter-Pace","version":"1.0","type":"link"}
