Should i fix my current bike or buy a new one? I bought a 2001 giant xtc at the beginning of the year to get into mtb. According to the guy we bought it from, he has replaced the tires, rims, cogs, fork stem and handle bars. 
I rode it for a few months, took it in for a tune up and ive ridden it about 6 times since.
Ive run into some problems these past few rides. My chain keeps skipping/ catching and itll randomly devide to jump gears. 
My headset/or front stem is basically screaming anytime i hit a root or jump as well. Ive swapped out stems and had it all cleaned but it didnt fix the problem. 
So would it be better for me to get a new bike( thinking about the 2018 giant talon 3, or around that same $600 price range) or to spend the money to fix the old one.
