Cartridge tubes sit inside the fork leg and do the actual damping. Outer tubes hold the bushings and the seal head, so their bore finish matters as much as the inner tube's outside. Inner tubes carry a low-friction coating; once it is through, the seals wear quickly.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. An original part keeps the unit within its published specification; a near-equivalent quietly moves it. Where a number has been superseded, Öhlins states the replacement — we pass that on. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21005-06 in this case. Check dimension a 36 mm, dimension b 86 mm against what you have removed; a close size is not the same part. Bushings in the fork carry the side load; play there shows up as knocking under braking. A bent inner tube is scrap — straightening changes the wall and it bends again.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 21005-06\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 86 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":53652452671754,"sku":"21005-06","price":4100.0,"currency_code":"BDT","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21005-06_3bd7696e-a6ef-40a0-9d6b-105a238d2e02.png?v=1788879219","url":"https:\/\/inter-pace.com\/en-bd\/products\/ohlins-inner-tube-36-86-al-21005-06","provider":"Inter-Pace","version":"1.0","type":"link"}
