Im sure ive seen this bike, and it looked so mint. to be honest this blokes being abit of a cuckin funt. Im with what anzo said, he's probably taken it to his bike shop and asked for a service and they 'think' they've found something wrong with some parts and seeing as this bloke seems to know nothing about bikes they've taken him for a ride and charged him for more expensive parts and hes now trying to take you for a ride. Just send the stuff back and completey ignore it, itl go away.
