i'm ebraised to say what i have invested in the actual bike but there are a lot of BRAND NEW parts:
bottom bracket
pedals
cranks
derailur
cassette
chain
saddle
bar tape
bottle cage
power grips (great for commuting in nice leather shoes)
and these parts are like new:
chain rings
front brake
stem
headset
shifter

total investment is less than $300
