Cool. And those are actually really decent looking STIs. I'm used to seeing the bulkier ones with the large rounded off front section. Should look really good on the bike!
I'm building an old 531 frame that I'm hoping will come in at 20lbs or less. Under 20 would be nice, but I'm being realistic and since I don't plan on putting anything really high end on it, 20 is the realistic goal. Lightweight vintage steel FTW!
As you know, make sure to post lots of pics when the bike is complete!
