Okay, so I'm sort-of in the market for a new bike. While I won't be able to make a purchase for several months, I may as well start researching (or, well, salivating) now. It'll be a fun bike, that much I know. (My current "fun bike" is becoming a commuter; it's time for her to grow up a little, like her rider.)

So, can I get some input on what I'm considering here? I don't know much about SRAM or wheels, for a start, so any help on that will be appreciated. I'd like to look at Trek if I get the chance, but I don't know a dealer around here.

Here they are:
Cannondale CAAD9 Feminine 5
http://www3.cannondale.com/bikes/10/...el-0RW95C.html
Pros: Cheapest out of the bikes I'm considering. Most aesthetically pleasing out of the bunch.
Shallow: the white and red that I would want (if I buy it in the next...8 months) coordinates nicely with BF's bike. We can be nauseating together. (okay, you can all stop gagging now!)
Cons: I don't know if I'm ready/need/how comfortable I'd be with something that's quite a bit more aggressive that what I currently have. No triple option.

Cannondale Synapse Feminine 5
http://www3.cannondale.com/bikes/10/...5C_0RWC5T.html
Pros: Carbon. Option for a triple. (I like my triple.)
Cons: Carbon. I don't know much about the relative merits of carbon, except that it's lighter and more expensive. Also not crazy about the paint, but the red's not too bad (assuming that I buy it before they run out of 2010 stock. They'll probably come out with something horrible next year...)

Cannondale Synapse Feminine 4
http://www3.cannondale.com/bikes/10/...el-0RWC4C.html
This is where it gets strange. The 3 is the Ultegra version. This is Rival. I don't know where Rival falls in the scheme of things, so any advice is appreciated.

Giant Avail 1
http://giant-bicycles.com/en-US/bike...ed/3881/36262/
Pros: Same frame as what I have now, but better components. It's familiar. Also, triple!
Cons: It's silly to re-buy the same frame, really, even though this option would cost less overall than to upgrade my current bike.

Giant Avail Advanced 2
http://giant-bicycles.com/en-US/bike....2/5683/37054/
Pros: Same geometry, but nicer materials. Also, nicer components. On the cheaper side, too.
Cons: Same geometry. I'm scrunched up on my current bike, I feel, and I'll see if adjustment makes a difference. I'm not tall enough to ride a "large", not that they make this bike in that size anyway.

Thanks for putting up with me posting another one of these threads...
