Valves and needles set the adjustable part of the damping; the piston sets the rest. Piston bands are consumables — they wear against the bore and lose their seal gradually. The seat face has to be flat enough for the first shim to seal against it.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. Every part in this catalogue is one Öhlins fits itself during assembly and service. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up. If you are between two sizes, send us the measurement and we will check it against the catalogue.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003e21054-15 is the Öhlins number for this position — the same one printed in the service documentation. This position has no published dimension, so the part number is the only reliable identifier. A worn piston band lets oil past the outside of the piston, which shows up as damping that has gone soft. Port area and shim seat geometry decide the damping curve before any adjuster is touched.\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 21054-15\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Valves\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":53652528562442,"sku":"21054-15","price":39.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21054-15_7bab904a-50c2-444f-842e-10b722fbdd1c.png?v=1788879455","url":"https:\/\/inter-pace.com\/products\/ohlins-valve-adj-mim-laser-engraved-21054-15","provider":"Inter-Pace","version":"1.0","type":"link"}
