Why do you ask? Well, it's not to get lower gears necessarily. I'm running an 11-32 cassette now and the 34-32 will get me up almost anything one time, like the 2500' climb 2 miles from my house. While on our tandem I'm resigned to the big jumps in our 11-32 (or 11-36), I find the jumps on my single interfere with the karma.
I'm going with a 12-27 cassette for regular, non-killer rides as the 30-27 will only be a few percentage points higher than what I had before and I really am going to like having the 16t cog. For longer and/or tougher stuff I figure a 36t cog will do the trick. If I can't get up a hill in 30-36 then I have no business riding that hill.
My 84 Miyata 912 had a triple and I don't recall way back then wishing I had something different. My son still uses that bike as his beater, but I'm getting it back soon. He's made some changes, but hasn't changed out the crankset thank goodness so I'll have two triples in my stable, N+1 so to speak.
My biggest concern is that with a triple I won't be allowed to post in the 41, but I'm figuring I'll still be ok here and in the C/A forum.
FWIW you can run a 13 starting cog and net an 18 cog too (13-14-15-16-17-18-19-21-23-26) and/or run a ring smaller than 30 (26x23 is the same gear as 30x27 and allows 12-13-14-15-16-17-18-19-21-23, and 26x26 or 27 is lower than 34x32).
I've mostly run a triple since noting in the 8 speed era that 50-40-30x13-14-15-16-17-18-19-21 meant a 7-speed corncob for plains rides and a low like 42x28 for mountains without wheel or cog changes.
