About a month ago I went on a ride where I would have normally taken my triple. Instead, I took my compact with a 12/28. As I was going up to the summit, I kept noticing 10% and 11% grades as I looked down at the computer. If I had know it was that steep, I would have taken the triple, (also with a 12/28). Didn't seriously consider turning back as there was plenty of daylight and I was in no hurry to get back ... and the fact that the summit was only a few miles more.

Even though I didn't get up very quickly, I was pleasantly surprised that I was able to pull a grade like that with only the compact. I haven't ridden the triple since, but might do so this next Sunday for my century because it is a bit more comfortable than the compact.

I had an 11/28 on for awhile, but really missed that 16t, so switched it back to a 12/28. 50/12 is fast enough for me now. I did the speed thing when I was much younger. Now, being safe to ride another day is more important.

That 12-30 Tiagra is intriguing. If it doesn't cost too much, I'll have to see if it will work with my D/A rear derailleur.
