Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 21905-01\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003eÖhlins publishes no separate dimension for this position, so the part number carries the identity. Öhlins builds click adjusters with defined detents so a setting can be written down and returned to. Preload adjusters carry the full spring force and are built accordingly. Öhlins publishes the click count for each unit, and a rebuilt adjuster should return it.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe part is identical to what Öhlins fits in production — same supplier, same specification. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. Send us the model and serial number of your unit and we will confirm the position before you order.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003ePart number 21905-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins does not publish a dimension here — go by the number and the exploded view. Needle and seat together meter the bleed flow; damage to either changes the whole adjustment range. Hydraulic preload adjusters are sealed units and are replaced rather than opened.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 21905-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Adjusters\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":53652020527370,"sku":"21905-01","price":67.14,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21905-01_e039f7cd-02d7-46d9-a01c-956138ca9002.png?v=1788878003","url":"https:\/\/inter-pace.com\/products\/ohlins-adjuster-comp-21905-01","provider":"Inter-Pace","version":"1.0","type":"link"}
