Okay I'm kind of a newbie, so bear with me here. This also isn't exactly an "electronic" so bear with me again. I like to bike long distances, and I don't have a gps or anything fancy like that, so I map out all the mileage on MapMyRide.com and write all the directions in VERY small handwriting so it can all fit on one index card. Then I tape the index card to my bike bar and follow the directions. But I have to squint and stop riding frequently to make out the words. My dad told me that there was a framelike device made for this type of thing that holds paper directions legibly out in front of the rider and that they make some that scroll down too, if you roll it. Does anyone know what this is called or where I can get one?
