Trek marlin 5 gen 2 Frame size is Medium Wheel size is 29 Drivetrain was serviced and chain has been cleaned and lubed every 2- 3 rides. Front brake is working but may need to be replaced at some point, back brake went bad on me the end of summer last year and replaced it with shimano and planned on doing the same with the front when that time comes. Typical mountain bike scratches but last summer the front chain kept coming off and scuffed some of the paint pretty good (you can see it at the front by the gear and pedals in the photos). I ended up taking it in to trek store in bountiful and they replaced a bunch of worn out parts that caused the issue and its worked buttery smooth ever since. I purchased this to get into mountain biking with my son as he joined a team but have upgraded to something that fits me better.
