so...I finally got myself a bike and had some potential upgrade questions.
First off, I purchased a Novara (REI) Forza. This has a road bike frame with a flat handle bar (nice and comfy for the bike path riding)
Components are as follow: Sora Rear, R443-B Front, 52/40/30 crank, Shimano SL-R440 x3 x8 shifters (front and rear). Not sure on the cassete other than it is an 8.
Now for the questions: I am sure in the future I would like to make some upgrades. How difficult would it be to upgrade to 105 or Ultegra? I know the chain, cassete, and crank will have to go. Can I get a 9 or 10 gear shifter for a flatbar? Would it be more cost effective to go to Ultegra or just get a new bike altogether down the road?
Another question: I like the flat bar, but would like a little bit of drop. However, not as much as a traditional drop bar. Would it be a cyclist no no to get a triathalon set up w/o the aero bars (bullhorns only)? Also, can you mount the flatbar shifters to this bar (I know new break levers would be in order)?
