I ride a cyclocross bike for commuting but want it to go faster! Instead of buying a new road bike, I'm thinking about new wheels & tyres. My journey is pretty flat at the moment.
The currents wheels are 700 * 35 and its using a 9 speed cassette with disk brakes.
So my question is, what are my options do I have , how small a tyre can I fit to the 35 wheel ?
