I used this 2nd-hand bike for 3 months, it has been always in GREAT condition!
I bought a new 31.6mm seat post to make it comfortable for anyone between 160cm(5'3") to 180cm(5'11").
Must sell since I am leaving Stanford.

about Trek's 4300:

"Trek's 4300 is perfect for riders just starting out in mountain biking and for cruising around town, commuting and running errands. Its Trek Black Series aluminum frame feels light enough to float yet is built plenty tough to hold its own in the durability department. Plus, this sweet ride boasts a 100mm-travel Spinner suspension fork for comfort and control, an easy-pedaling 24-speed Shimano drivetrain, a plush seat and super-versatile tires on dependable rims."
