for my Cannondale BB Ultra. I commute to work most days. I am switching out the derailleurs to road, a road cassette, bullhorn bars w/ STI 9spd shifters. Why - because. What wheel set can I buy that is 700x23c tire/rim laced to MTB hubs that are compat with Shimano road cassette. Or do I need to buy the rims sep and have them built. My LBS is Stadlers (largest in the world I think) and they want 300 euro for some Mavics with XT hubs. Obviously I would like to spend a little less. Any other tips on this conversion? are appreciated.
