3T ARX LTD stems
These look interesting, 3T have full carbon stems rated for MTB use that actually weigh less than hefty alloy stems. 118gms for a 110mm stem is not bad if it's actually not a noodle with wide bars.
Edited because I'm an idiot. I thought you were talking about the Edge stems. (also really nice and all carbon... but brutally expensive)
Funny, I was also looking at those stems, however they are expensive. The 3T Team stem in alloy is 120g for 110mm, 2g heavier, but at a fraction of the cost. One thing though, I do really like the way the LTD looks. On Looks alone, they are a top contender. Heck, who knows, I may still get one!
