Road bikes are usually geared higher to accommodate pedaling on high speed descents. Most of my commuting is under 50kph however. As such, I could easily get by with mountain bike or touring gearing on the front ring. I have never really needed or wanted anything larger than a 48t chainring.

An 11 speed cog on your rear cassette is a significant jump from a 12 and 13 speed cog, making it much easier (and inexpensive) to adjust your gearing simply by changing out the rear cassette.

If you have concerns about speed, which I think shouldn't really affect you at all, enter in the gearing into Sheldon Brown's gear calculator and see what happens with 80 and 100 revolutions per minute cadence. In most instances, your largest ring, with an 11t rear cog is going to put up around 50kph or more, which is plenty fast for most occasions.
