How do I install my new pedals? You can use a 15mm wrench for all pedals, some of them also allow for a 8mm Allen wrench to be used. One thing to keep in mind is that the left pedal is reverse threaded, so you screw it counter-clockwise to tighten, and clockwise to loosen - Remember to grease the threads. What is the advantage of clipless pedals? Clipless pedals work the same way ski bindings do, giving you are more solid interface with your bike. They let you use all of the power in your legs, both on the down-stroke and on the up-stroke. Clipless pedals will give you more power in your total pedal stroke, as without clips, you only have power when you push down on the crank. You can go faster, farther and climb better with less energy. Of course, clipless pedals take a little getting used to, but once you’ve used them, it’s unlikely you’ll ever go back to clips. Clipless pedals are actually easier to get in and out of than old-fashioned clips. You just position your foot over the pedal and twist and push -"click" and voila - you're "clipped in". To take out your foot, simply rotate and pull up- you'll hear that "click" sound. It's a motion that will come naturally with more riding experience. Most clipless pedals have a various degrees of "FLOAT"; Float is the amount of distance you foot can rotate before releasing. Float takes stress off of your knees while you are pedaling.
