Make a 6600 12-27 a 12-28 using 6700 11-28 cogs?
Has anybody taken off the 21/24/28 cogs off a 11-28 6700 and put them on a 6600 12-27 to make a 12-28? I hate to give up the 16 and do not need the 11 cog. Seems like it ought to work.

looks like it'll be a very straight forward swap, since the 12-27 has 21-24-27 on the spider.
just be sure to use the 12T lockring from the 12-27 cassette.

From the tech documents that I could find it appears that you can do that. The 11-28 shows to be all individual cogs except the largest three.
Personally I would much rather have the 16 than the 11. But I'd also rather have the 12-27 than a 12-28. It just depends on where you ride and what you need.

Personally, I'd prefer to have tighter spacing on the low end than have a 16 tooth cog. Shimano's 11-28 has 19-21-24-28 and SRAM's has 19-22-25-28, but the BBB and IRD 12-28 cassettes have 19-21-23-25-28 (but no 16 tooth cog). I ride in the mountains a lot, so find tight spacing on the lower gears to be essential, your typical riding situation may make other parts of the cassette more important to you. Of course, with a Campy 12-29 11-speed then you can have the 16 tooth and the close spacing at the low end, and one extra tooth! Bliss!

I expect it will work but it seems awfully expensive to gain one tooth. That's less than a 4% improvement.

My LBS tells me that Shimano is coming out with 10 speed mountain bike stuff and will allow a larger cog set that one can put on road bikes.
