Hi guys! I'm new on this cycling word. I just bought this bike used, and apparently i need to do a few adjustments on it to fit my needs and fix some wrong previous setup ( Ex: Change Shifters and get a wider Handle Bar and maybe new high rise steam). My questions is , i did pay $350 for the bike, its worth to do those changes (Almost $300 plus in parts) or should i try to sell it and get other bike? Was the price a good price for this setup? Sorry if sound stupid, but I'm really newbie on this subject
