This guy knows what he is talking about. Her seat was too low but she has a nicer setup now (Raleigh comfort hybrid) and is really getting into riding now.

I want to get smoother tires but I do a good amount of "off road" riding on gravel and grass (abaout 15-20% of my ride) so I don't think that would be a good idea.

Like JR said, aero affects the ride A LOT. So it is more like uphill both ways. It is just absurd when I get upwards of 25-30 miles per hour.

I will get an updated picture of my "aero" mod but don't hold your breath because it's not all that impressive. I'm in the process of finding a new headlight and computer. I've got two more hybrid bikes just sitting there at the moment so I'm going to try to trade for a road bike this summer.
