Rear spring rate sets ride height, static sag and how much of the damper's stroke is actually usable.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e77 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 75 N\/mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 01093-21\u003c\/li\u003e\n\u003cli\u003eInner diameter 57 mm\u003c\/li\u003e\n\u003cli\u003ePowder-coated yellow\u003c\/li\u003e\n\u003cli\u003eFree length 150 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy the Rate Holds\u003c\/h2\u003e\u003cp\u003eProduction is Öhlins' own in Sweden, and the tolerance on the rate is what separates these from a generic replacement. The finish is applied after setting, which means the coating does not affect the rate. Production has stayed in Sweden since the company was founded in 1976.\u003c\/p\u003e\u003ch2\u003eSize and Rate\u003c\/h2\u003e\u003cp\u003eDimensionally this is a 57 mm × 150 mm spring; within that envelope Öhlins offers a range of rates, and this one is 75 N\/mm.\u003c\/p\u003e\u003ch2\u003eWhere This Rate Belongs\u003c\/h2\u003e\u003cp\u003eA firm rate keeps the fork high in its stroke under braking, which preserves the geometry when the front is loaded hard. Heavier riders, two-up use and track days all push the choice towards this end. A firm rate holds the chassis attitude when the front or rear is loaded hard. Road surfaces are the hardest test of a spring rate, because the fork has to cope with both a smooth stretch and a broken one.\u003c\/p\u003e\u003ch2\u003eRate and the Linkage\u003c\/h2\u003e\u003cp\u003eBecause the linkage is progressive on most modern machines, a small change in rate moves the sag more than riders expect. A shock absorber spring carries the whole rear of the machine through a linkage that multiplies its rate several times over — which is why the number on the spring looks so much larger than a fork rate. Rear spring rates run in the tens or hundreds of N\/mm because the spring sits at the short end of that lever, not at the wheel.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eRather than a model list, use the measurements: a fork that accepts this diameter and length is a candidate, and the rate follows from rider weight. Nothing about the installation changes across a rate range: the mounting, the length and the bore stay the same. A spring is one of the few suspension parts that is genuinely interchangeable: same bore, same free length, and it goes in.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eÖhlins supplies a setting sheet with the springs; the numbers on it assume the specified oil. Check the free length against the old springs before fitting — a sagged original often measures short. The springs come powder-coated and need no preparation before they go in.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: none is issued for springs as such — they replace an existing component of the same function. Any model-specific approval is listed under Applications.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins suspension rewards careful fitting. We recommend having the work done by an authorised Öhlins service centre — and we are one ourselves: we fit, service and set up Öhlins components in house. If you would like us to handle the installation, just ask and we will quote it with the order.\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 01093-21\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSpring Rate:\u003c\/em\u003e 75 N\/mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFree Length:\u003c\/em\u003e 150 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 57 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eStroke:\u003c\/em\u003e 77 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eConstruction:\u003c\/em\u003e Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFinish:\u003c\/em\u003e Powder-coated yellow\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":53645337821450,"sku":"01093-21","price":75.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/RearOhlinsSpring_ba712364-4445-4743-8cf0-5058ee204355.png?v=1788866656","url":"https:\/\/inter-pace.com\/en-uy\/products\/ohlins-shock-spring-75-n-mm-150-mm-57-mm-01093-21","provider":"Inter-Pace","version":"1.0","type":"link"}
