The adjuster is the part a rider actually touches, and its detents are what make a setting repeatable.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 21050-40\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eÖhlins publishes no separate dimension for this position, so the part number carries the identity. Electronically controlled adjusters replace the needle with a solenoid but keep the same hydraulics. Hydraulic preload adjusters are sealed units and are replaced rather than opened. Needle and seat together meter the bleed flow; damage to either changes the whole adjustment range.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e21050-40 is the Öhlins number for this position — the same one printed in the service documentation. Where no measurement is given, the drawing position is what identifies the part. Compression and rebound adjusters are not interchangeable even when they look similar. Hydraulic preload adjusters are sealed units and are replaced rather than opened.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 21050-40\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":53652526235914,"sku":"21050-40","price":17272.36,"currency_code":"HUF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21050-40_a5326c9b-ad76-423d-b0f4-5e9877b8ff04.png?v=1788879447","url":"https:\/\/inter-pace.com\/en-hu\/products\/ohlins-knob-compression-adjuster-21050-40","provider":"Inter-Pace","version":"1.0","type":"link"}
