I just got back from a pretty decent trail ride on my new Kona, and I noticed that there is a sizeable gap between my crank arm and the opening to the bottom bracket; like about 1/4". I have had the bike only 2 days and didn't notice it, but it looks like a good amount of dirt, sand, and gravel could get in there and tear things up. Am I missing a seal, or some sort of spacer that covers this? I don't want to have to take the cranks off and clean out the bottom bracket every time I ride.
Here's a few pics of what I am talking about; sorry if they are unclear, my camera is not good with macro:
Please excuse my pathetic MS Paint skills...
