Anyone else race singlespeed in a standard race bracket against mostly geared riders?
What advantages and disadvantages do you find yourself saddled with against them?
How well do you typically finish?

I'm curious because I started racing CX this year as a Cat-4 35+ and I'm usually 1 of only 3 or 4 guys in the field (60+ per race) without derailleurs. For a first year CX racer with no previous experience in any type of bike racing I'm not disappointed with where I'm placing, but I've noticed some distinct strengths and weaknesses of being the singlespeed guy in a geared field:
Strengths:
- No dropped chains. Even on the worst of bouncy, bumpy courses running too much pressure in my tires and hitting ruts like I get paid to try and break my rims, I haven't dropped my chain.
- No gear jam-ups, skipped/missed shifts. Well, duh; no shifting == none missed.
- No snagged components. I've seen guys get rear derailleurs snagged on sticks and even tall grass on some of the real jungle-cross courses.
Drawbacks:
- Spinning out my gearing on flat sections. Getting passed on the downhills or outsprinted by geared riders in the final 20 yards just sucks.

That's about it that I've seen for drawbacks. How about anyone else? I got outsprinted on the finish stretch this weekend by some geared guys, and I've been passed on long flat straight sections before. I find that I can often power out of corners better than the geared guys, but that's likely to be a product of the Cat-4s and guys hitting the corners in really low gears. Between hammering out of the corners and being quick over the barricades and remounts I manage to stay in the top 25% (but I'm averaging about 2 minutes off the leader's time.) Not really in position to challenge the podium guys, but not bottom of the heap, either.
