New to the group. Sorry if this is an old question for those veteran mechanics out there!
I have an old (about 10 years) Giant carbon frame bike that I'd like to upgrade to 9 speed 105 STI with a triple crank.
If I am planning on upgrading everything (FD/RD/shifters/crank/BB/cassette), is there any reason this is impossible (i.e., any geometric limitations on older frames)?
I also know that some suggest to sell this bike and buy a new one with the components I want.
The reason for wanting to do this is:
1. Improve my limited mechanical skills.
2. Finding a low priced carbon frame isn't terribly easy.
3. Sentimental reasons. I could never sell her.
Any thoughts are appreciated!
