I have a question for the gallery:

I have a bunch of Shimano stuff that I'd like to be able to keep while experimenting with crank arm length.  Are there any third party cranksets with multiple length options that also support Shimano direct mount chainrings, and aren't significantly more expensive?

Shimano's new XT and XTR cranks are available down to 160 mm which could be what I'm looking for, even though that's only 5 mm shorter than the preceding model.

I was sure that I'd read the new Deore cranks also have a 160 mm option, but now I can't find any information about them.  Were they mentioned in any of the press kits?

White Industries revealed last week, I think, that they're working on expanding their cranksets down to 155mm. Previously they had 165-180.

Just incase anyone was interested, the samox alloy dh cranks are a few months away. 

I really don't know why you'd go for carbon ones here, 2.5x the price, alloy ones are going to deal with rock strikes way better and with the current trend of hanging weight off your BB why not just buy heavier cranks?
