There is no "standard triple cassette" although many manufacturers will use a 12-25 (though that is the same regardless of crank at least for midrange bikes). 12-27's might be becoming slightly more popular, though this is based solely on looking at Cannondale's 2008 Synapse offerings. I have a 12-27 with a 52/42/30 triple on one of my bikes and love the gear range.
