I got this as my first mountain bike earlier this summer, and have been happy overall. It rides and handles well.
I was wanting a bike with both front and rear suspension and this fit the bill. I wasn't as worried about weight, so the aluminum frame was fine.
The shifters work great. I'm sure they're not the fastest at shifting, but it has never been a problem.
The only issue I've had is with the breaks. When I first got the bike the rear break was soft and wouldn't engage unless I pumped it a few times. I took it in and had them bled. They worked better after that, but now they are getting soft and I have to pull them in quite a bit before they engage. I anticipate breaks being the first component I have to replace on this bike.
I have had no problems outside of that, and have put many miles on it already.
