Certainly looks like a Noleen to me.I need your help… is this an AMP or a Norleen shock?

That hard anodising and the diagonal knurling on the preload ring don't look like AMP.
All the best,

NBI on the spring and that grey color is bog standard noleen. NR1 means no adjustments all the way up to NR4 with rebound and compressionThanks. I contacted Noleen and they told me it's an NR1 with an 8mm shaft.
