Looking for something lightweight (hollowtech or similar)
Thinking XTR double with just one ring or something like a E Thirteen [url= http://www.chainreactioncycles.com/e-thirteen-trs-race-am-direct-mount-crank-arms/rp-prod114903 ]TRS single[/url]
Middleburn RS8 x-type?
Those E13s do look light.
I'm tempted by old XTR polished up.
+1 RS8 X-Type, with a mono spider and whatever chainring you'd like.
The E13's are crap, don't bother. I have a pair and they refuse to stay tight. also the retention bolt is really wide and I hit my ankle bone on it a lot.
Those new Aerozine ones look pretty good and the subtler colours aren;t too bad on graphics.
Another vote for Middleburn RS8 X-Types, with a uno ring, so it's spiderless, just bolted on a set and wow they are sexy, love them.
