I'm thinking of that super-fat rider that you posted in the FID thread.

But sure, a heavy rider picks up more momentum going downhill, but if there is a flat stage after a downhill, how long will that advantage last? The increased air drag, etc. should kill off the advantage after a while, right?

.... and what about the braking distances? Even Dura Ace calipers aint gonna do too well if you're talking "that super-fat rider that you posted in the FID thread" - disk brakes front and rear me thinks with custom super soft compound slick tires.

If it is a really long descent, even disk brakes may not help, and drag brakes may be required - of course not feasible in a race (which would disqualify the "super-fat dude" from participating in such a race me thinks ). It is the same problem with tandems - can't use rim brakes or even disk brakes for long descents.

DuraAce Calipers=105 calipers. It's the pads and rims that make all the difference.

So how do tandems get down mountains then? Do the riders make like Fred Flintstone and Barney Rubble and don some slate soled shoes and give it some serious foot on floor action?
