Outer tubes hold the bushings and the seal head, so their bore finish matters as much as the inner tube's outside. Fork legs are matched left and right on most Öhlins forks and are listed separately. Axle clamps are machined so the axle clamps without pinching the fork out of alignment.\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 is one of the few suspension makers that still supplies every position in the exploded view as a single part. For a full rebuild, the seal kit plus the wear parts is usually the sensible order. 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\u003e21630-01 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states dimension a 43 mm, dimension b 50 mm, dimension c 54 mm for this number, and those figures are the deciding ones. Öhlins publishes tube diameters by fork model, and they are not interchangeable across the range. Axle clamps and lower legs are machined to hold the axle without distorting the fork.\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 21630-01\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 43 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 54 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":53650659508490,"sku":"21630-01","price":240.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21630-01_d6402cb6-46b4-4750-a783-084f66198e22.png?v=1788877311","url":"https:\/\/inter-pace.com\/en-lu\/products\/ohlins-fork-leg-outer-43-50-54-508-21630-01","provider":"Inter-Pace","version":"1.0","type":"link"}
