Coffee makes me incredibly hungry (any caffeine does). This would backfire on me soooooo bad.
I have to wonder if an extra cup of any liquid per day would help avoid weight gain. You hear so much about people misinterpreting thirst as hunger - they eat instead of drinking.
Are you talking about internal hubs? There are many bikes with internal hubs available in the US, far more than bikes with Pinions. Even department/sports stores like REI sell bikes with internal hubs. I have 4 bikes with internal hubs, one is a CVT which is a hoot to shift but heavy as heck.
