Just checking up on the weight of the double FC-M785- anyone here have actual weights?

Upgrading my girls mtb cranks from the heavy FC-M542's and want to see what sort of weight savings can be achieved. I would also consider the FC-M985 XTR double if there is a reasonable weight reduction.

FC-M542- 960 g with BB (I believe)
FC-M785 XT double -740g (Competitive Cyclist listed weight, BB included or excluded?) EDIT- Bike24 list these as 810g with BB which is less impressive...
FC-M985 XTR double 'Race'- 629g (Competitive Cyclist listed weight, BB included or excluded?)

So best case scenario that's a 331 g reduction if you go from M542 to XTR, sounds good right?

EDIT- May have just answered my own question, found this: http://www.birota.ru/files/news/2010/xtr-weight.pdf
So XTR FC-M985 is 715g

Making best case scenario 245g.

Thoughts on this being a good area to reduce weight?

FC-M785, 40/28, 175mm: 733g
BB: 92g, with 3x 2,5mm spacer.

Installed those yesterday.

Thanks for that rainerhq.
So XT are about 150g lighter than the Deore M542's.

Here you have weights of whole group

My 175mm XT M785 26/28 came to 721 grams. BB was 91.

I understand that the XT double (and bash) uses a thicker axle than the triple, so if you are WW it start with a triple even if you intend to bash it......plus the Shimano bash is very heavy, circa 150g
