I tried an XT cassette a while ago, but ended up bending the larger cogs (and before anyone asks, no I wasnt in the big front ring and the big rear cogs when I bent them)
Saddle and post are standard enduro spec (post is 2014 alloy according to the spec sheet).
The bashguard was the one area I was thinking might be cheap to save to weight, so any suggestions there are very welcome.
Scottchegg – to a certain extent I think you're correct, and this will probably be as far as I go with the weight loss programme, but I'm just checking that I havent missed anything obvious, it was ~36lb before I started on this.
