I was in REI when I saw a bike, the novara strada at a really good price. It had 105s all over, and it cost $900. With the exception of a couple deals from supergo, this is the best price i've seen for a full 105 bike.

The frame, however, is made of AN6 aluminum, which I've never heard of before.

what can you guys (or girls) tell me about AN6? I dont mean for this to be a frame material debate, but what is the deal with AN6?
