Hi again,

Thanks for all the valuable info.

I have a very basic time/speed/trip/counter type computer on my bike. I think that I am riding in a reasonably efficient manner. I have found that the more I ride, the more I am getting a feel for the gear that suits me in different situations. Have tried to count revolutions and I think I am riding around the 90/minute (perhaps slightly less) mark most of the time. On assessing body positon and movement, I don't think I am mashing, as my riding is smooth and I am not aware of any jerking body movement. I think I am more likely to jerk when I have less resistance. When I began riding I was not able to comfortably use the gears I currently use now. I guess that is an indicator of muscle develpment somewhere!
