Look at Chavanel/Horner at Stage 10 of this year's TdF, or O'Grady/Geslin on Stage 6 in 2003. Last year's Paris Tours winner, Erik Dekker, dispatched his companion over a k before the line, probably knowing that a sprint between the two of them would have only let the field catch up.
Indeed, two man breaks seem almost doomed from the start, even if they do manage to get close to the finsh line.
