Thread size identifies where it belongs on the unit. Öhlins builds click adjusters with defined detents so a setting can be written down and returned to. Compression and rebound adjusters are not interchangeable even when they look similar.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. The alternative to a service part is usually a new damper, which is why this catalogue exists. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21907-02 in this case. The published dimensions are dimension a 1 mm, dimension b 17 mm — measure the old part against them if you are unsure. The adjuster is the part a rider actually touches, and its detents are what make a setting repeatable. Electronically controlled adjusters replace the needle with a solenoid but keep the same hydraulics.\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 21907-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Adjustment Housings\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 17 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M29x1\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":53652965949706,"sku":"21907-02","price":31.36,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21907-02_7eaa1a00-8b0a-4434-9f46-dab0524715cc.png?v=1788880438","url":"https:\/\/inter-pace.com\/products\/ohlins-adjustment-housing-m29x1-17-21907-02","provider":"Inter-Pace","version":"1.0","type":"link"}
