Road bikes tend to have a more aggressive riding position and narrow tire width. Their geometry is more aerodynamic, which enables you to maintain higher average speeds and cover more ground quicker.
Many race and triathlon riders look for speed when choosing a road bike, so the lighter the bike, the better. If you’re more interested in comfort than speed, a fitness or hybrid bike model may be a better choice for you.
