while zumba was kind of rude about it, I agree with him.
road bikes are better for riding on the road. theres nothing that says you need to have your bars 10'' below your seat like a pro. If you can afford a road bike, I highly recommend it. It will be about 10 pounds lighter than your enduro, have more hand positions for comfort and will be sooooo much more efficient.
Heck, you might even start wearing spandex and shaving your legs!
