Full suspension mtb

Diamondback release 1 size Large. Here are the specs if brand new. https://99spokes.com/bikes/diamondback/2021/release-29-1 -Stock parts except new wolftooth dropper lever, new raceface chester pedeals, and 2 new (less than 50 miles) maxxis holy roller II. set up tubeless. -Some cosmetic scratches (pictures included) from cable rub, bike lock rub, or normal wear and tear scuffs - ridden hard for about a year until I upgraded to a new bike (haven't touched in 2-3 months) - bike is trail ready and good to ride today HOWEVER if this was my bike I would having shifting serviced (shifting is a little clunky if trying to move multiple gears quickly) - Suspension has never been serviced/and something creaks sometimes when pedaling under load (bottom bracket I would guess but don't know for sure) - brakes feel good Not firm on the price. Let me know if you have any questions
