I have the California Coast section 4 in front of me. The smallest writing measures out to be about 5-point which is plenty big for my 49-year-old eyes w/o bifocals in outdoor daylight, but I haven't tried to read it with the vibration of a non-perfect road. I don't have a handlebar bag though, so I'll be pulling it out of my jersey pocket to look at it, so the vibration probably won't be an issue. If each map were very much wider, it wouldn't fit in a side jersey pocket. As it is, I don't think a handlebar bag map pocket would be big enough to see two of the little pages at once. It never occurred to me that some people wouldn't be able to see it. Have you tried it in standard outdoor daylight yet (which will make the pupils smaller and improve the focus)?
