The outer tube holds the bushings and the seal head, so its bore finish matters as much as the inner tube's outside.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eDimension C 573 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 21941-02\u003c\/li\u003e\n\u003cli\u003eDimension B 54 mm\u003c\/li\u003e\n\u003cli\u003eDimension A 50 mm\u003c\/li\u003e\n\u003cli\u003eFinish: black\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003e50 mm, 54 mm, 573 mm: that is the whole specification, and it has to match what came out. 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. A marked inner tube destroys seals repeatedly until it is replaced.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. Send us the model and serial number of your unit and we will confirm the position before you order. Where a number has been superseded, Öhlins states the replacement — we pass that on.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21941-02. Öhlins states dimension a 50 mm, dimension b 54 mm, dimension c 573 mm for this number, and those figures are the deciding ones. Inner tubes carry a low-friction coating; once it is through, the seals wear quickly. Öhlins fork parts are specific to the fork model, not interchangeable across the range.\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 21941-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Outer Tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 54 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 573 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFinish:\u003c\/em\u003e Black\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":53652141211914,"sku":"21941-02","price":352.34,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21941-02_71308c7b-977d-4e22-9f29-8068e780bd2f.png?v=1788878128","url":"https:\/\/inter-pace.com\/products\/ohlins-outer-tube-50-54-573-black-21941-02","provider":"Inter-Pace","version":"1.0","type":"link"}
