I love Aluminum bikes.
I have two built up now. An Allez Special Edition and a Van Dessel Hellafaster. (I just pulled apart a CAAD 12 Black Inc to finish a Carbon bike build)
Here is what I looked at, it's a short list.
LOW bikes. (Made in the USA)
Vynl Bikes (Made in the USA)
Van Dessel Hellafaster (Made in the USA by Zen before they went out of business there are still frames available)
Specialized Allez Sprint Special Edition (Made in Taiwan)
CAAD 12 (Made in Taiwan)
Get the LOW. So sweet looking.
