Or do you find yourself wanting to go for maximum potential and trying to fit a 28-32T max cog in the back? I know we're talking about a 28T presently, but this goes for other builds. I will admit to chasing the 1:1 or better low-combo, even if the reality of a 12-23 or 12-25 rear gearset is ideal for cadence-to-effort fine-tuning. Something that Campagnolo, with their 13-26T 9- and 10-speed cassettes, are really good at. I remember one Port Angeles ride (60 miles total, out to The Hook) with the Miyata 1000 where I really enjoyed being a human CVT with that rear gearset.
Generally, I like to have a 30 inch gear for hilly rides and I've been known to go as low as 24 inch (which led to
aggiegrads making the classic remark that his 24 inch gear is two feet). The hill up to my house is 1/4 mile maxing out at 20% grade. Anything less than 30 inches and I am using the "two feet" gear. Fortunately, most of the hills around here are in the 3-7% range.
