I'm putting together a coil spring project and digging through my box o parts, I found an unlabeled spring. The spring that came off the shock was labeled as 650x2.25. The exposed shaft length is 2.0. The unlabeled spring is about an inch shorter than the 650, but the separation between coils is the same or better on the weird coil.
1) is there any way to know whether I will experience coil bind on this spring aside from "ride my bike" and finding out?
2) is there any way to determine spring rate on this coil? It puts sag at about 30% according to the built in doo-hickey on the stays, but that is very much not accurate. Calculators tell me I need about a 500lb spring.
