Shimano came out wiith 11-28 this year and that is what I am now using and it's awesome.
JB:? Will a standard older derailleur (Ultegra in my case) work with the 11-28 or does it take a longer throw derailleur or something.? I thought there was a max tooth difference front + rear or something techie like that which limited the the range of the rear.? In my case it doesn't much matter 'cause even 12 is too big for me, just curious.
Also, tell us some about your bike(s).? Triathlons or pure bike races?

Shimano literature indicates there may be a problem, but, consensus is Shimano is just being conservative. You should look up the exact model of your Ultegra rear. Do you have 9 or 10 speed? My bike will be ready today, so I intend to test the new compacts in hills shortly. My rear is a 26, so going to a 28 is a future possibility.

This thread is a "long strange trip" from Rons new 4x4's.? PS - I predict they will be "minty" when resold. Maybe I should get in line now.
