I'm not familiar with the terrain you ride but you'll probably be okay. I ride both the 53/39 and a 50/34 and the 39 will work for most terrains-except very hilly with longer climbs. I'm not sure but it would probably not be hard to replace the 39 with something like a 36 as another option. The 50/34 compact would allow you to use that setup for all types of terrain, however. Even riding some steeper hills in the mountains.
