Fork tubes are the structural part of the front end and carry the braking load into the yokes. Axle clamps and lower legs are machined to hold the axle without distorting the fork. Fork parts are specific to the fork, not to the motorcycle it happens to be fitted to.\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. Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. We can check the number against the Öhlins exploded view before you order — just ask. 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\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21005-21 in this case. Öhlins states dimension a 36 mm, dimension b 161 mm for this number, and those figures are the deciding ones. Diameter and length identify the tube; both follow the fork model. A fork tube that has been bent 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 21005-21\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 161 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":53652454572298,"sku":"21005-21","price":379.0,"currency_code":"TTD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21005-21_5efc6960-a7a2-4511-bff4-e882c54c1eee.png?v=1788879232","url":"https:\/\/inter-pace.com\/en-tt\/products\/ohlins-inner-tube-36-161-al-21005-21","provider":"Inter-Pace","version":"1.0","type":"link"}
