Mustache of course but very nicely shaped on a VERY cool rig. Bike is Baaaad ! I'd be too afraid to steal it.
Just kidding... I wouldn't.. I'd ride it ! I'm no longer an e-bay Zombie but I must say that as I told the man , they're are stores in e-bay if you explore the stores themselves, not the auctions per say.

There are Mustaches and there are Mustaches... Yours have an up, then a down then straight back.
I call type "an aggressive bend" Two basic themes of Must. PLUS Scrod's & others minor variations.
Yours look like 26.0.. not sure. THe STRAIGHT BACK come in both 26.0 & 25.4(1") The 1" (25.4) come in the gentler bend mostly. I have yours on a Ti. race bike that I downgraded to a commuter.
I have your pedals too, kind of. Looks no better than yours, that's for sure.
