beng1 that sounds right. On those fast flats - you know, where it's downhill enough to go fast, but not enough to coast - we'll hit 32+ mph. Even with the 53/15 I feel like a mouse on a wheel. I can hold 120 or so for bit, but end up peddling in bursts - enough to stay on the wheel; without messing up the guys behind me. Fortunately those sections don't make up much of the route.
