Hi and thanks to everyone who replied. I rode it for one hour earlier this week on a beautiful sunny day and i could keep up with my husband! Wow, cannot believe what a difference there is compared to my old clunker: lighter, faster, clips give me more strength to pedal....the only thing I am a bit fearful of is going downhill and feeling like I'm going to fly off forward when i apply the brakes and then more stress on my arms....Will let you know.
