Within a month of buying my first bike last year, a hybrid with a 48/38/28 triple, I knew I wanted closer ratios. I didn't like the big jumps between the gears, and it seemed like in many places, the gear I wanted was the one between the ones I had. Fortunately, my usual terrain doesn't require wide ranges. I replaced the 8-speed 11-30 with a 13-23 and was happy, until winter when snow and snow tires required the big cogs again.
The 8-speed 13-23 is a rare item apparently. I couldn't find another when I bought my road bike (52/42/30) this past winter. So it got a 12-23 and a 12-28 for when I get into the hills south of the city. Recently, I moved the 13-23 from the hybrid to the road bike and am enjoying the 16-tooth cog again. Still wishing for an 18...
I have a new bike on layaway, a Trek Portland. I comes with a 52/39/30 triple and a 10-speed 12-27. I'll be ordering a 13-25 for the nice weather. That'll finally get me the 18-tooth cog I've wanted for a long time. Before snow flies, I'll be getting a 16-27 for it. Yahoo! Close ratios at the low end for snow riding.
With 16 months under my belt, I find I'd continuing to get stronger. That has me thinking about a double for next year. Not yet sure if I'll give up the triples, or if I do, if I'll go compact or standard.
