Hello I have a 2022 Trek 820 black and blu steel frame. I rode it only for few months (from around Oct/Nov 2023 till now) upgraded myself with a full suspension so this is an extra bike i have. It served me well everything is original, tiers still have lots of life, I change front a rear tubes, V brakes works perfectly and  pads are barely worn. Original Shimano shifters great quality change gears smoothly. I put a trek shock absorber poster sit. Front fork travel is 75 mm . The whole bike It’s been checked and maintain multiple times from the shop I bought it from so it is in great shape really. They discontinued this models but it’s a great entry level mountain bike that it’s been around for many years. Great use to commute, maybe weekend rides with friends and fam or ride trails that aren’t too technical (which I rode also). Feel free to reach out for any questions.
