This is an early 2000s Specialized Allez Elite. The frame is made from enhanced butted aluminum, while the fork is made of nice lightweight carbon (this adds a "buttery" feel to the ride).
This measures approximately 54 cm center to center horizontal top tube (measured manually, so take that with a grain of salt).
Features a very nice Mavic Ksyrium Elite wheelset with armadillo anti-flat technology road tires.
I include the Bontrager stem (100 mm), the clip pedals, and extra tubes that go with the bike.
Shifting works well on this Shimano 105; it's a little sticky in the front shifter, but that's because there is a huge after-market gear in the front for extra power.
The only other sticky point is that it needs new bar tape.
