Looking to either upgrade to new bike, or components... Little help?
This is a long time coming but I've been upgrading my bike, a 1994 Bianchi Eros, and I think I've hit a point of no return. I have little experience with new road bikes since I have stayed with steel-frames since I was 12, and my first bike was a 57cm Trek 400, the Bianchi being my second bike. Total. This one is currently running Shimano RX-100 groupset at 7 x 3 speeds.
Reason for upgrade is because I broke my hand/arm a few years back and its getting to be a pain to keep going back down, even when riding for leisure. That AND I got a nice bonus from work that I am splitting between my gaming computer, and bike.
I need help with deciding what to do:
* Bring new life to the Bianchi and get a new 10 speed grouppo (Ultegra/105) with either STI shifters or Gevenalle CX2's and cable stops to upgrade the Bianchi... It would save me a good chunk of change and leave my bike feeling new. Also thinking of getting a Quill-Threadless adapter and get a new stem/handlebar... So recommendations all throughout. THIS BIKE HAS SENTIMENTAL value, as it was build up by a late friend of mine and myself, and I would like to keep on using it, so I can DEFINITELY justify spending more money on it.
* Get a new bike within an $1000-ish range that has all of the things I would like, and leave my Bianchi untouched for leisure rides... Willing to spend a bit more if definitely worth it, but bang-for-my-buck is the way to go, as a college student.
For further detail, I am looking for brifters (tired of downtube) and a lighter overall ride, for the SF Bay area terrain... I am generally scared of Carbon- being 6'5", over 240 pounds and them being expensive does not sound like a good mix.
Thanks for any and all recommendations, and excuse the wall of text!
