I own a 2011 roadking deluxe. Recently I have been facing some issues with my bike. To rectify this issues I m thinking of doing the following upgrades
1.The seat bolt becomes loose after riding short distances and it is very frustrating so I m thinking of getting a new seat post
2. It is hard to shift gears due to the downtube mounted shifters and the right brake lever has become loose I m considering installing brifters
3.Also during a recent bike ride the derailleur screw came loose even though I dont shift very often and did not mess with the screw
So should I upgrade this bike or buy a much better aluminium frame bike
The first question is, do you really love your bike? If yes, then why not upgrade? Yes, the price of STI levers are half the price of your bike.
The screw that hold the rear derailleur? It probably came loose due to corrosion (my best guess).
Right brake lever has become lose? As in, what way?
Consider of converting your Roadking deluxe to single speed it will serve your purpose well if you don' shift much.
