Tig Welded Aluminum.
Rear brake bridge and cable guides(tig-ons?) on the top tube.
1 1/8" Head Tube.
Trackish Geometry.

I'll ignore the shop reputation here, but it is something anyone considering this frame should research before buying this frame.

Pros:
It's stiff and nimble. With the right wheelset and fork you can build this up for a reasonable price. The ride can be a little harsh, but at this price point I believe saddle, fork and tire choice make a bigger difference. Mine is a ton of fun to ride, I feel like I'm on a rocket when I mash down off of a stoplight.

Cons:
The welds are pretty standard for an imported AL frame. I opted for the clear coat which actually looks like a yellowish shellac. The frame was barely prepared before the finish was applied. There are actually 1-2 fingerprints underneath the clearcoat on this frame. The rear cable guides are welded to the top tube so it would be tough to remove them without damaging the frame. The complete prices on the website seem a bit high.
