I am a super newbie to racing and did my second race ever this past weekend. I did reasonably well all things considered, but I dropped my chain several times. The course was REALLY bumpy so I figured that may have been a factor, but I am wondering if there is some other cause, i.e. technique or a chain issue. It was always on the small ring and always to the inside, though couldn't tell you where on the cassette i was when it was happening. The chain is only about a year old, so I wouldn't think it would be totally stretched out.
I did not have this problem at my first race, so I would appreciate any insight on how to prevent this in the future.
