The Synapse 5 Alloy has alluded me. Can't be found anywhere in Bay Area.

I did find a 6 Alloy that has Tiagra. It is priced well below MSRP. Is it even possible for me to take the 6 and swap out the components to 105? Is it even worth it? How much would I expect to pay to do that?

I rode the 5 disc today. I just love the feel of the bike. I rode a Z5 maybe? First. It was a men's and I did like it better than the womens version of the same. But then I tested the 5 Disc. It felt so good- until I tried to brake. I nearly got hit by a UPS truck as I couldn't stop even with the levers depressed completely. I immediately went back into shop. They confirmed brakes were not working well and said maybe they needed to be tuned. And another guy said it is common for disc brakes to take a few weeks to break in. No way am I taking 3 weeks to break in brakes! It sucks because I can't even say I will wait for the 2015s as they will all have disc.
