Anything lighter or in 11-42 about the same weight.

328g for the XTR – the Sram XG-1175 cassette is lighter, has the 10-42 range, and the freehub, though it’s an additional cost, will save a little too

Thanks but looking to stick with 11t and the existing freehub.

XTR about as good as you’ll do then. Sunrace fo 11-42 options btut they’r enot light, nor is XT

GX cassette in the cheaper 1150 version is a bit heavier than the above, but still lighter than XT, great value IMO

Cool, thanks for the input. Xtr is is then.

Recon do an 11-40 that’s 263g. Won’t last or shift well though.
