How long does the post need to be? It seems that I have enough to cut and save some weight.

The MINIMUM INSERTION MARK tells you how much has to be in the seattube.Use a felt tip to mark present position in the seattube. Remove post. measure from MIM to end of post. Measure that distance from felt tip mark and cut. Don't grow any.........
2.5 inches...C-40

Is the distance marked on one of my posts. If you cut off a couple of inches maybe you'll save 1 or 2 seconds off your next 2 hour ride.

No, that last part is a joke- but you know, it really wasn't to try to save weight- it was just the aesthetics of it all...
I had a cheap Kalloy post that came with a used bike I bought. It must have been about a foot and a half long. It was probably made that way so it could fit into a variety of frames, or whatever reason the manufacturer had.
Anyway, it was stupidly long and ridiculously over-sized for my application, so I cut it down. Yeah, it cut a few grams, and I felt good about that, but that wasn't the point. It's a fairly reasonable thing to do, along with other bike details like tidy cable housing lengths, wrapping your computer wire nicely, or a clean bar-tape wrap. You sure aren't going to save enough weight to affect your ride times, but it feels good to know all that extra length is gone.
