Thanks for the replies on what type of bike I should be looking at. i think I am going to try changing the tires to slicks, and a few other little changes, try it this way for a while, checking out other bikes in the meantime. We are getting into cooler weather here in northern ontario, and the biking is great. 70 degrees in daytime, a lot cooler at night. I am not a lover of the 85-90 degree stuff. Enough hot flashes of my own to keep warm. Thanks again Lori
