This bike arived exactly in a week i've been riding for a month now with this bike all in all this bike is great except for going through innertubes a lot. The tires are ok if you are a very carefull rider if you are extreme outgoing rider I sugest you buy upgraded tires for this bike same goes for the inner tubes, get thicker innertubes or get tire liner so you would get a less chance of getting a flat be prepared for the stock tires & inner tubes. It is super light frame & with a upgraded carbon fiber fork it would be even more lighter instead of the steel fork it It comes with. Overall I give this bike a 8.5 out of 10 (Posted on 9/26/11)
