Öhlins specifies a defined number of clicks per adjuster so a setting is a number, not an impression. An adjuster that turns without resistance has lost its detent; the setting is then guesswork. Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe part is identical to what Öhlins fits in production — same supplier, same specification. Suspension is one of the few areas where the original part is genuinely the cheaper decision. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. Öhlins parts are unit-specific: a close dimension is not a substitute.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e21972-01 is the Öhlins number for this position — the same one printed in the service documentation. The thread is M8x1. Preload adjusters carry the full spring force and are built accordingly. The adjuster is the part a rider actually touches, and its detents are what make a setting repeatable.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\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 21972-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Adjustment Screws\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M8x1\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":53653153644810,"sku":"21972-01","price":30.25,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21972-01_eb050386-61b9-4cdb-a7dd-fbfd3ba24d82.png?v=1788880584","url":"https:\/\/inter-pace.com\/products\/ohlins-adjustment-screw-m8x1-left-66-21972-01","provider":"Inter-Pace","version":"1.0","type":"link"}
