HG70 vs HG90 cassettes

[Dr Dremel]

Yep (not so) shiny ones are HG70, shinier/chrome are HG90. The problem is to recognize them when you don´t have a HG90 to compare as the HG70 alone can already look quite glistening.

Another hint can be the lockring sticker: On the HG90 it just says "HG Hyperglide" whereas on the HG 70 it has the "CS-HG70" denominator printed on. Of course lockrings can easily be swapped and most used ones have the sticker missing anyway.

Different background (well, underground in fact) color on the lockring: silver for HG70, gold for HG90.

I can instantly recognise the hg90’s but struggling to identify this? It came off an XT M732 hubbed wheelset that I’m sure was on from new..
