i hover right around 200lbs usually, perhaps a tad under if i've been riding a bunch. here's my road setup...
frame: salsa campeon
drivetrain: campy centaur (chorus rear der), 9 speed
bars: salsa pro road
wheels: bontrager race x lite (rear), velocity aerohead / american classic (front)
pedals: used to use look cx-6, these days it's shimano ultegra spd-sl
no complaints, really. for the power i can manage to put out i can't perceive much flex outta the frame. the thomson stuff is rock solid, as expected. the bars are strong enough for me, but i have a feeling someone stronger/bigger may find them a little on the flexy side. if i weren't trying to get rid of this bike i'd probably switch over to a 31.8 bar/stem combo to stiffen things up a little bit.
full build comes out to between 17 and 18 pounds.
