I'm looking to put a better climbing cassette on, and the 11/28 appears to be a solid choice. My current is 12/25 cassette Ultegra.

Anyone care to comment on spacing of this setup and if I'm on the right track for good spacing on gears without to much gap? Would I need a chain replacement?

Thanks,

Assuming you're running 10-speed cassettes, here's how they (usually) break down:

12-25:12-13-14-15-16-17-19-21-23-2511-28: 11-12-13-14-15-17-19-22-25-28

Look at your most-worn cogs on your 12-25 along with the ones just adjacent to them and see if those are still present on the 11-28. A lot of the time you give up the most-used cogs when increasing a cassette's range because the ones deleted are right in the middle.

You may not have issues with the actual jumps between gears, but if you're not already using the top end of your cassette, there's no need to go higher. SRAM 1050 has a 12-27 that maintains a lot of the same middle cogs, and a 12-28 that's similar but with that one extra at the low end.
