TREK Mountain Bike Carbon Fiber

I built this Trek mountain bike myself about 8 years ago, using top-of-the-line parts. I spent around $7000 on it initially and have maintained it properly every year since. I used it mostly during summers, about 15-20 times each summer, but never for long rides. Given the effort put into building and maintaining it, I'm confident the buyer will be very satisfied with this bike. Type: Mountain bike, Brand: Trek, Wheel Size: 26 in / 650c, Frame Material: Carbon fiber.
