The cylinder is one of the few damper parts that is genuinely wear-limited. Twin-tube dampers use two concentric tubes, and both are listed separately. Diameter and length together identify the tube — both are specific to the damper it came from.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Order by part number — descriptions repeat across sizes, numbers do not. If you are between two sizes, send us the measurement and we will check it against the catalogue.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21646-02 in the exploded view for the unit it belongs to. Check diameter 30 mm, length 34 mm against what you have removed; a close size is not the same part. Bore finish decides how well the piston band seals; a scored tube leaks damping past the piston. The tube is what the whole damper is built around: everything else references its bore.\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 21646-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDiameter:\u003c\/em\u003e 30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 34 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":53650842845450,"sku":"21646-02","price":98.11,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21646-02_ac27f57a-491d-414d-943c-470818abf1e1.png?v=1788877403","url":"https:\/\/inter-pace.com\/products\/ohlins-cylinder-tube-30-34-275-21646-02","provider":"Inter-Pace","version":"1.0","type":"link"}
