I wasn't afraid either. Been using SPDs and then Shimano road pedals for ever. They were so much easier than the toe straps and Power Grips that I learned with (for me - not for everyone).

I'd just like to comment that once you have the motion down on the trainer, the next best thing to do is to go to a GRASSY PARK/LAWN and practice, not a parking lot. That way, if you do have a fall, the landing will be softer. Don't worry - your road bike can handle riding on the grass .

Good luck!
