So I will be purchasing my first road bike tomorrow, likely the Scott CR 1 Pro. Next issue is pedals and shoes.

On my mountain bike i have Crank Brothers candy pedals and use Shimano shoes with the two holes in the bottom. The cleats i use are Crank Bros. as well, http://www.jensonusa.com/Cleats/Cran...m-Pedal-Cleats
I don't know if these are what are called SPD type but my shoe says SPD and the cleats fit. If not SPD what do i call these??

I like the pedals because they can be clipped in on either side. As I research road pedals it looks like only one side can be used.

Question is: can i use Crank Bros pedals and similar shoe on a road bike or do i go for "road" pedals? If so, why? Bad form to use mountain bike pedals or not a big deal ?

I will likely stick with Shimano shoes as my feet are wide and the Shimano shoes fit quite well. O.K. to use a spare mountain bike shoe or better to go with a stiffer road shoe. Remember I'm new to this so what is my best course of action.

Thanks for your help.
