Lesson Learned: Clipless Pedals Are Way Different Than Flat Pedals

Some of you may remember a post from a while back when I spoke of getting my mountain bike. I was debating what I would do for Pedals. I couldn't decide ultimately how I was going to set up the bike in terms of pedals, that's to say flat pedals or clipless pedals. I am starting to lean more, much more, toward setting the mtb up clipless. While I was out on it the other day, and as I was bouncing around the trails and hills, i felt myself pulling my foot up as I'm used to doing on my road bike. On the road bike I'm used to pulling my foot up on the pedal on the upstroke, on the mtb I found myself pulling my foot clear off the pedal at times. Other times I found my feet bouncing off, or rolling the pedal over as I rode the particularly bump sections. I also find myself re-centering my foot often on the pedal. To further add insult to injury, or in this case injury to insult, not only was I riding sketchy because I kept wanting to lift my feet clear off the pedals, but I've done so so many times that I've bashed my calves and shins enough times to, at times, waddle like a penguin. So I guess what I'm trying to say is...
Lesson Learned: Clipless pedals seriously help your circles when pedaling. Also, once you are used to them it's hard to ride without them.
