120mm full suspension 27.5+ that can also take 29er and 26 fat wheels. I have a Bucksaw, and it is near perfect except that a touch more travel (120 vs current 100) would be nice. I think there are a few bike like this on the market now. Lenz/Trek/Spec maybe? Right now I am really smitten by 27.5+, because it has 85% of the benefits of full fat in a lighter, more compact package.
