My bike finally came and it's a sweet one. It's a 2010 Gary Fisher Superfly 29er. Carbon fiber frame and 29 inch wheels. Well, when I first rode it yesterday, I did notice a big difference because of bigger wheels than a regular 26 inch wheeled bike(my old bike). It was harder to accelerate but it's supposed to ride better on the trails so since there are still snow on the ground here, I haven't really tried it on the trails yet. So hopefully the snow will melt soon so I can try it! Everyone on their 29ers has been telling me that you have to be on a gear or two lower than on a 26er wheel bike but on this bike, it's supposed to be so light that on this one, it doesn't do such thing, so you are still on the same gear and go a little bit faster. The bike is at 21 pounds(now that is light). I guess I read about this gear thing in a bike magazine and I kind of noticed it on the ride yesterday on the climb on the canyon road. I don't know for sure so I have to ride it some more though. My old bike is 26 pounds that is a 5 pound difference, that is a lot though. I love the brakes and the Sram shifters and deraillers. The carbon fiber crankset is full of awesomeness. The bike fits me better than my old bike because Klein bikes make longer top tubes so I am not really leaning forward too much. Well, it's a great bike.
