Fork tubes are the structural part of the front end and carry the braking load into the yokes.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDimension B 57 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eDimension A 48 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 21668-01\u003c\/li\u003e\n\u003cli\u003eDimension C 58 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eThe published figures are 48 mm, 57 mm, 58 mm. Measure the old part against them before ordering. Öhlins publishes tube diameters by fork model, and they are not interchangeable across the range. Outer tubes hold the bushings and the seal head, so their bore finish matters as much as the inner tube's outside. A fork tube that has been bent is scrap: straightening changes the wall and it bends again.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eAn original part keeps the unit within its published specification; a near-equivalent quietly moves it. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Where a number has been superseded, Öhlins states the replacement — we pass that on. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21668-01 in the exploded view for the unit it belongs to. Check dimension a 48 mm, dimension b 57 mm, dimension c 58 mm against what you have removed; a close size is not the same part. Axle clamps and lower legs are machined to hold the axle without distorting the fork. Bushings in the fork carry the side load; play there shows up as knocking under braking.\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 21668-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Fork Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 48 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 57 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 58 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":53651287769354,"sku":"21668-01","price":257.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21668-01_af12ad5d-97cd-45aa-8415-bf527feb5152.png?v=1788877643","url":"https:\/\/inter-pace.com\/en-pe\/products\/ohlins-fork-leg-outer-48-57-58-543-21668-01","provider":"Inter-Pace","version":"1.0","type":"link"}
