Ironman Kansas 70.3 : Official Thread (Page 12)

I don't know why you would even think of riding an 11-23.  What does that 11 really get you and what do you give up if you needed that 27 for some reason.  Really do you think you are going to be pushing that 11 super hard down a hill.  going from a 12-11 isn't that much difference and I doubt you'll care if you max out your bike speed downhill at 45 instead of 47.  But you might hit a steep hill where that 27 might come in handy.  I'm not saying that hill with a 23 would be that bad, but at least you have the option of saving a little juice. 

Anyway thats my $0.02.  Oh and if you have been riding in a 12-27 you might look at what the other gears are on the 11-23.  I know when I switched to my 12-26 from my 11-23 the gear that I always pedaled in (my smooth gear) wasn't there anymore and it took a while to get comfortable. Just sayin....Nothing new on race day right?

Last I heard, they are going to measure the water temp at 4:30am Sun. I would be surprised if the temp was not at 78 or less. When I swam today, it did not feel too warm for a wetsuit.
