The cylinder tube is the working bore: the piston runs inside it and every damping force is reacted by its wall. The tube carries the end cap threads, so damaged threads mean a new tube rather than a repair. The tube also carries the end cap threads, so thread damage means a new tube.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eA damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. We can check the number against the Öhlins exploded view before you order — just ask. Order by part number. The dimensions below are the ones Öhlins publishes for it.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e21006-05 is the Öhlins number for this position — the same one printed in the service documentation. This position has no published dimension, so the part number is the only reliable identifier. Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load. Reservoir tubes carry the gas charge and are built to the same standard as the working cylinder.\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 21006-05\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":53652458307850,"sku":"21006-05","price":58.17,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21006-05_c44e1741-d64b-4eb8-9de7-d236f2621d4e.png?v=1788879250","url":"https:\/\/inter-pace.com\/products\/ohlins-cylinder-tube-81-fe-21006-05","provider":"Inter-Pace","version":"1.0","type":"link"}
