I'm not a racer, but can usually keep up to the cat 3-4's pretty easily. This bike has been outstanding. Its responsive and super light. It has dura-ace throughout and I have done very few upgrades beside the wheelset.
The Helmet provides good air flow, and is lite for its size. The best thing is how it protects you in crashes. I have crashed several times with this helmet and has always taken the hard blow instead of my head.
Unfortunately this bike was stolen from me, but it served as a catalyst to get me into cycling. It's a great intro bike to get you out on the roads and give you a real feel of just how awesome it can be to spend an afternoon of freedom cycling. I highly recommend this bike to anyone looking to spend less then $1K.
