There is now a Mountain Bike Rides iGoogle theme available. If you use iGoogle as your homepage in your browser you can now use this free theme which has been approved by Google. The colours are based on the styles for this site and the banner photo changes every couple of hours throughout the day.

Click here for the theme in the Google library or just choose "Change Theme" and search for "Mountain Bike" on your iGoogle homepage - it's normally the first one you get back and called "Mountain Bike Rides Theme".
