Strengths:    Light weight, sturdy frame, good components for beginners.

Weaknesses:    gears, forks

Bottom Line:   
I have owned mine for approximately 7 months and have ridden it fairly hard on trails and the road, I am overall satisfied with the bike. I just recently upgraded the forks to Rock Shox XC 32's which is my first set of Rock Shox. You can tell a huge difference in the ride. I have had issues with having to adjust my gears several times due to the mud and wear and tear.

Strengths:    Frame, handling, light weight.

Weaknesses:    Brakes and the CRAPPY SUNTOUR FORK. Tires aren't good for cornering, you can go down pretty easy

Bottom Line:   
I tried a great deal of bikes before getting this one. It was the lightest in the budget range I had at the time. I am just getting start and am entering a couple of local races. I don't ride it on pavement at all. But after all of the upgrades I made to the front of my bike those parts are worth more than what I paid for the whole bike. But what really matters is that I am pleased with it. And I really am.

I must mention though. about a month and a half of riding and while riding this bike the upper part of the fork came out of the lower casting. This could have broken my neck. I just want people to be aware. I didn't crash this bike very hard or anything or jumped it off anything more than a foot. Be very cautious of the fork. The Trek store warrantied it and they were very good about it. But I don't trust it anymore and that's why I upgraded to a fox float and had to change out the front hub to accommodate the 15mm thru QR.
