Rollers to diagnose bike setup?
I've caught a lot of flak already for running a 60mm -10deg stem and risers, with people claiming they're really unstable, etc. etc.
My rollers finally came in today, and good lord! My bike IS really, really twitchy on the rollers. But it definitely doesn't feel like its that much on the road.
Discuss.

I don't do the bike fitting at the shop for nothing, you know. I just built my bike with the pieces from a 49cm frame and didn't bother to put a longer stem on because I like the upright position in traffic.
I'll put on a 110 -10 tomorrow and see what happens.

.....Or just experiment with a stem that's "right" for the bike? 5'10", 56cm frame.

Go to work, and play around with it myself until it "fits".
I've ridden the bike with a 140mm -10 (which was nucking futs) and drops. I'd ride it like that on the track, but the decreased visibility in traffic wasn't worth it. And I've mostly ridden it with the 60 with both bullhorns and risers. It all depends on what ride qualities I'm aiming for. I have leg extension and knee angle all perfectly dialed in, along with saddle tilt and fore-aft position. And all of those did change slightly and were corrected when I played around with the 140mm stem.

Now tell me again that this bike (minus the joke HED3 and plus a few minor part tweaks) doesn't fit me.

ok, so you know *all* about fit and you've got it dialed...that much is apparent now. 
proceed to step 2 in my previous post...form.
rollers are a *****, but it's not the bike's fault.

20 miles tonight definitely helped a lot.
Although admittedly, 60mm does feel a bit short after a while. Experimentation to follow!

Also
Visibility is good but these bikes aren't meant to be ridden sitting bolt upright. Ride risers if that's your style but at least get a stem extension that doesn't put 100% of your weight on your ass. Take some time to get used to the more aggressive posture your bike is meant for and you'll probably find you actually like it once you get past the adjustment from what you're probably used to.

Blacksburg has a population of 39,000 people, how heavy could the traffic be?

I'm not quite completely upright, but definitely after an extended ride I start to feel somewhat.... cramped in my current cockpit setup. That, and the lack of hand positions starts to suck.
I guess it all eventually boils down to context. Shorter, casual point A to point B rides are great with the short stem and risers setup, but roadie-esque training rides (rollers or road) probably should be done with a legit "road" setup.

I think you said you were 5'10"? If so a 100mm stem will be perfect for you. I have the SE Lager as well, the crap stem that came with it I think was 60mm, just way to small. I went then to 90mm, still didnt feel right, then to 100mm, perfect! I have been measured anyways and 100mm is suitable for me.

I'm ending this once and for all.
I brought home the Salsa Size-O-Matic from work and a set of drops. This ought to be fun.
