aluminium cassette sprockets?

[02GF74]

Are these avaialable?

I realise they will wear out quicker and what will the weight saving be?

Not planning to buy them just curious,.

You def get titanium. I picked one up the other day and they sure are light. About 180 quid though

IIRC, Marchisio made cassettes with titanium for the smaller sprockets and aluminium for the larger ones.

The carrier on my dura-ace cassette is aluminium and I think the larger sprockets are Ti.
