I bought a road bike a week and a half back and I've done 120KM on it already. I park and ride, drive part way in with the bike in the back of the ute and ride the rest. I'm doing about 30KM a day. Did a couple of rides locally and 3 days riding to work so far. I hate exercise generally but I'm enjoying this.
I bought a carbon framed HASA. It's a Taiwanese frame (Most of the big name frames are made there anyway). Despite it's origins the quality seems top notch. All the running gear is good stuff. Shimano 105 and Mavic Aksium wheels etc.
It weighs 8.2KG which is probably less than half the last road bike I owned.
My theory was buy something fairly decent to start rather than a $500 commuter bike bike because if I stick at it I probably would have bought something better anyway. I'm very happy with it so far.
Cheers
