Thanks, guys! Sorry for the slow response--I was out of town visiting family for much of the last week (which was a lot of fun) and was thus unable to access BF. The Sirrus is indeed a classy looking bike, especially if you put shiny pieces on it! I am leaning toward the Sirrus frameset's fate being that of residence in a new loving home. It's been fully gone through, built up, and vetted, and is thus worthy to continue to be on the road, providing many smiles to its new owner. From Shimano 105 and a clamp-on FD to C-Record Campagnolo and a braze-on FD mount--movin' on up!
