Its reckoned you only have to run a third of your bike ride for the same effect, but this is a very rough estimate depending on terrain etc.
I run too and my average run is approx 40 mins 10km, this is adequate to maintain a good level of fitness over the winter. But a 40 min bike ride is nothing :-)
Dunno but money talks and people like Garmin, Sky, Radio Shack have lots of cash.
Plus the bike manufacturers get the publicity by letting teams use their bikes.
I designed the paint scheme myself, thats the good thing about custom. Brian is a really nice bloke, and has so much experience, he takes ages measuring you, and the paint finish is top notch :P
