customizing shimano 11 speed cassette?
I am running 10 speed 7800, but now that 5800 is out I am thinking of saving for that.
I run 53/39 cranks with a 12-27 or 12-30, depending on the elevation.
Shimano makes an 11-32 cassette, which starts out 11,12,13,14,16
It is possible to swap the 11 for a 15 and get 12,13,14,15,16 instead?
Will this degrage shifting? I don't know if the 11 speed cogs are ramped or whatnot.
Thanks!

All recent Shimano cassettes from 7-speed on up have the cogs ramped and designed to work best with specific adjacent cogs. So, yes, swapping out a different cog will effect shifting. That said, I don't know if individual loose cogs are available, particularly in 11-speed form. It's likely they are not.
If you are going to switch over to the entire 5800 group, consider getting the compact crank(50/34) so the 11T won't be quite as useless or stay with the 12x30 or 12x27 cassette and have a usefully lower low gear.

Have to buy 2 11s cassettes and cannibalize one, it better mean a lot to you, since it wont be cheap.

I assume 11 speed is like 7 to 10 speed in that the end cog has a built in spacer.
So, if you want a 12T end cog you need one from a 12-? cassette..
Typically, changing just one cog on either end doesn't effect shifting too much. because any indexing problems would only happen on the extreme end of the range and the end cog indexing position is controlled by the high limit screw. (and your largest cogs are often on a "carrier" which prevents swapping just one.
Using different speed cogs in the middle of the stack will effect indexing.
You're probably better to stick with 10 speed.

need a new brifter to shift an 11 speed too so you will be dropping a chunk of change.
you got plenty?
