Title: Finding heavier springs for NR-4
Post by: JonAre on August 18, 2006, 01:22:27 am

A friend of mine is concidering buying my K2 Proflex 4000 frame from 1998, but the spring on the NR-4 rear shock is a bit to flimsy for him. As far as I can tell from http://idriders.com/proflex/resources/99spring_chart.pdf I would like to get my hands on either a NM175-600* or a NM175-650* spring, used or new. Can anyone help me out?

spring science is a very well known subject.Take one of your springs into any spring place and tell them what rate you want.Callum at rdi might be able to supply one too.Or iron horse for that matter
