Awesome Bike, Bad Rims
Rating:
The Good
I use this bike for XC trails and some mild trail riding around Richmond, VA. The trails I ride are fast, flowy, and smooth with a few small jumps sprinkled in and some mellow rock gardens. The bike has felt incredible on the trails. It's stable at speed, excellent at the climbs, and doesn't shy away from some air time.
The Bad
I do think there are areas that could certainly use improvement. First and foremost, the carbon rims. I have owned and ridden the bike for a month. The trails I typically ride would not cause a person riding a full rigid bike much discomfort. Unfortunately, the Bontrager rim failed and cracked. Fortunately, the rims is covered by warranty. With the current state of the industry, a new one is not available until February. Obviously, this is a massive bummer because that means I have to wait six months to ride a bike I have had for one month. Now, I am a seasoned rider and definitely do not shy away from using a bike to it's full capacity. I do not believe I was using the Trek beyond its capabilities and strongly believe that the rim should have held up to the type of riding I was doing on it. It's possible that my rim was simply defective, but that is a fault that cannot be ignored and is worth noting. Hind sight being 20/20, I would have placed CushCore on the rims before ever riding it. The extra 150 bucks would have been worth the estimated six months off the bike I currently face. Beyond the rim, I think the XR3 tires are not the best in terms of grip or strength. Likewise, having extra hard points on the frame to mount accessories would have been nice.
Overall Review:

The bike has been fantastic and I would recommend it. It's a blast to ride when it has wheels!
