I just got the cateye v3 speedometer. It has a good few features including speed, cadence and heart rate sensors and runs on a 2.4 ghz band which makes it interference free and allows you to mount the speed sensor for rear wheel.
I am thinking of getting a new bike soon. I have been looking at both the giant defy composite and the bianchi vertigo. If there is anybody that is good on their bikes reading could you please leave a comment on which one is better. I know the giant has better components compared to the bianchi but I am more interested in the frame and ride quality.
