Just picked up a NOS 2007 Unit 2-9 and boy howdy do I like those 29 inch wheels. They making rolling over things a breeze. Anyways I must have come down on a rock pretty hard a few days ago, but the dustcap from the bottom bracket/cranks popped off and is nowhere to be found.
This is the first time I've seen a hollow bottom bracket; it's an FSA MegaEXO bb with an FSA V-Drive crankset. Is the dustcap necessary for anything besides keeping gunk out of the hollows? Should I get a new one? My LBS didn't have one in stock so what should I do?
Thanks in advance.
