The obvious downside is that you lose the 11-tooth cog. On a flat course I find it beneficial. OTOH, it kinda sucks on a hilly course because most of the time when you shift, you need the bigger gap between gears.
Trying to secure one in either before the weekend race. Local shop has both the 11 and 12 starting cog. I just ran the "gear speed cadence" calculator, and looked at my recent rides on that bike and I haven't used the 11 cog. So I told them to hold the 12-25 for me.

It's flat enough on the recon ride I never got slow enough to need a 28.

Last night it was constantly like, ughhhhhhh here we shift again. Too much, too little. I was cruising like between 22 and 25ish on some rollers and kept skipping 15 to 17 on the 11-28. I needed that 16t.

Glad that this thing is in the morning (heat). I should be on the bike and out of T1 by 8:40 including my AG start and the initial run leg time. Assume 25min of run and up to 15 min delay starting.
