I received a used road bike that functions, but not well. I completed a triathlon and lots of practice rides, but wanting to upgrade the components.
The crankset is ultegra 6500/170m. The shifters and FD are ultegra (prob 6500 too?) and the RD is tiagra. Not positive about the cassette (is there models markings there somewhere?)
My goal is to slowly upgrade (based on budget) to either 105 5800 or ultegra 6800.
1) can I upgrade the shifters, FD, and RD and keep my existing crankset and cassette for upgrade later? 2) is there an upgrade path that lets me upgrade a few components at a time to eventually get me to a modern groupset? 3) best place to get affordable parts?
The frame is in great shape. Aluminum with carbon fork. Bike weighs in at 19 lbs, fully loaded. Shimano rims, etc. Would prefer to upgrade this bike.
