Trek 820 Single Track 21 Speed order Mountain Bike

Product Name: Trek 820 Single Track 21 Speed order Mountain Bike
PLEASE Read and Look At Photos! — I am selling this Used Trek Single Track 21 Speed Mountain Bicycle. The bike has a 21” / 53.5CM Frame. It belongs to my niece's friend and he used it at college. It has a small order ding in the top tube(photo 9) and some scuffs both are from the lock he had to have on it to secure it from being stolen at school. It rides, brakes and shifts good, the bike shop did recommend the chain be lubed, and maybe a good tuneup. , but will let new owner do that. They also noted the right shifter lever that sometimes the gear indicator sticks or does not works at all, they said that may need lubed also? It does not effect the functionality of the shifting itself. It is a good - quality Used Trek bike. I will disassemble the handlebars, seat, front wheel and pedals for safe shipping.
