While commuting? 30 or 31 MPH on the fixed-gear.

I've broken 40 MPH a couple of times on long downhills. Given a long enough hill, you're limited only by your aerodynamics, your weight and the rolling efficiency of your bike.

I ride with a couple guys who are 200lbs.+ and that's what they say. Really anything approaching 35 and I start to feel uneasy.

~31 mph of flat with no wind, but only for a few seconds. At that speed, about 630 watts is used to overcome air resistance. To hit 37 mph, I have to output about 1050 watts (1.4 hp) to overcome air resistance! A world-class track sprinter can output about 2000 instantaneous watts.

About 26 mph on flat and I've hit 32 downhill a few times.

Well then if we're talking strictly about commuting then it's *maybe* 30mph on a downhill, as were the other speeds I posted. Personally I don't think those speeds are anything to brag about. I probably get close to that speed every commute since that's the way I take. And I'm not necessarily trying, just coasting, so again nothing to brag about there.
By the way, its a discussion forum. Let's discuss.

38MPH on my road bike, downhill. I felt pretty comfortable but when I told my wife. She was like "WHAT?!?!" that is so fast. My kids were impressed haha I too would like to break 40mph
Fastest commuting I have no idea since I don't have a computer on my commuter or mountain bike.

Always on the edge of being late to work, so often pushing it. OTOH I'm never fast in the morning :/
Fully loaded down a hill in New Zealand last year I hit my all time speed record.

Level ground/no wind, about 32 MPH. Same on both my road bike and my crappy/heavy hybrid - top speed really shouldn't depend on the weight of the bike, but aerodynamics. On the road bike I can SUSTAIN 32 MPH longer, but really not that long.
With a tailwind I can hit 34 to 36. Downhill I've been up to about 40. I just run out of gears with my old bike. I haven't had the road bike long enough to have it on a significant downhill in good weather.
