By using clipless pedals/shoes, you'll gain a powerfull mechanical advantage and your feet will be in the optimal riding position every time.

When you use a clipless system, you have the ability to pull your pedal stroke back up instead of just pushing down when using flat pedals. This helps is all kinds of situations like climbing and going fast!

In addition, when using flat pedals, what do your heals do everytime you pedal? They drop right? With a clipless system, the majority of shoes out there consist of a rigid sole so when you pedal your heel stays horizontal with whatever angle your pedal is. This all points back to power and efficiency.

Obvious disadvantage include:
-Falling becaue you can't unclip
