OK! So, my bike is about 2 months old and has around 2,100 miles on it. I used a Park chain checker and it says my chain is in need of replacement. At this point throwing a new chain on will definitely cause some wicked chatter as the chainrings and cassette are showing signs of worn teeth. So should I
A) Suck it up and replace the entire drive train every 2 months or so? EXPENSIVE
B) Replace JUST the chain and the big chainring because that is the one that shows the most wear and I use the most. Allow for chatter when in other gears until the chain wears in on the old gears.
C) Ride it till it doesn't work and then replace it all.
