The smaller piece that fits inside the larger piece is what attaches to the bike. The side with the grooves for the o-rings is the side that makes contact with the bike. The smooth side fits into the larger (outer cover).
This is not an easy bolt-on installation. I had to make numerous adjustments and modifications to get mine to work. Fortunately once its on, there's little reason to ever remove it.
Hope that helps
