Nice conversion, sweet bike!
It's cool to see a contemporary Specialized Sirrus, especially in dropbar trim.
I have (what I was told) a late 80s/early 90s Sirrus being refurbished and updated. It was about to be trashed. This was a full road race spec bike, 105 7 spd SIS, Tange tubing. Not like the hybrid of today.
I can't find much data on these old Specialized bikes online. Plenty though on the celebrated Allez.
