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\u003ePowder-coated black\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00180-97\u003c\/li\u003e\n\u003cli\u003eMeasured spring rate 27 N\/mm\u003c\/li\u003e\n\u003cli\u003eStraight-wound, constant rate\u003c\/li\u003e\n\u003cli\u003e126 mm of usable stroke\u003c\/li\u003e\n\u003cli\u003eInner diameter 46 mm\u003c\/li\u003e\n\u003cli\u003eFree length 220 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow Öhlins Makes Them\u003c\/h2\u003e\u003cp\u003eTwo units carrying the same part number behave the same way out of the box, which is the whole point of testing each one. Öhlins machines its own critical components instead of buying them in, and the tolerances are where the money goes. Öhlins winds, heat-sets and then measures every spring individually — the rate on the label is the rate you get.\u003c\/p\u003e\u003ch2\u003eThe Numbers That Matter\u003c\/h2\u003e\u003cp\u003eAt 220 mm free length and 46 mm inner diameter, this spring is dimensionally interchangeable with anything of the same size — the rate is what makes it a different part.\u003c\/p\u003e\u003ch2\u003eChoosing 27 N\/mm\u003c\/h2\u003e\u003cp\u003eThe trade is fork dive under braking — noticeable, but rarely the limiting factor on the road. Comfort and grip come from the spring moving early; this is the end of the range where that happens. This is the end of the range where small-bump compliance matters more than resistance to diving. Ride quality on the road is decided by rate first and damping second.\u003c\/p\u003e\u003ch2\u003eHow a Rear Spring Works\u003c\/h2\u003e\u003cp\u003eA 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. A spring that has settled in service sits shorter than new, which quietly lowers the bike and steepens the steering. Preload adjusts sag within a rate; it does not change the rate, and no amount of it will rescue a spring that is wrong.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eThe safest way to choose is by static sag: set the target figure, and the rate follows from whether you can reach it with preload. Selection is by measurement. If the diameter and free length match your fork, the remaining question is the rate. Sag figures, not feel, decide whether a rate is right. Öhlins publishes the targets for its own units.\u003c\/p\u003e\u003ch2\u003eWhat Fitting Involves\u003c\/h2\u003e\u003cp\u003eNote the original oil level before draining — it is a useful reference even when Öhlins specifies its own. Fitting is a fork-oil job: the legs come apart, the springs go in, the oil level is set to specification. Once fitted, ride the machine before making damping changes: the new rate alters what the clicks do.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: not applicable to the spring on its own. Öhlins issues approvals against complete suspension units, not individual springs.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting matters as much as the part.
