I run 29-13, and next time I get a new sprocket I'm going 30-13.

In my very humble opinion 28 is too easy.

I'm running 28/14 and I like it, but that's probably because I used to do a lot of XC and road biking and in those sports a high RPM is favored over higher amounts of effort.

2:1 is far too high. Spins too easily, you have to put in so much work to keep up a decent speed.

Not for me. 70-100 cycles per minute tends to be what us XC/road riders would do. You really notice how much effort you still have one hour later riding at almost the same pace.

I just did some quick calculations and to my surprise it appears as though I've been running a 1.3:1 ratio on my long distance rides, which is so surprising that I think it's incorrect, but this is for sure: I would never do long distance in a high gear.

its a 2.0 ratio with a 3.8 gain ratio. I like this for ss XC too. I am going to build a ss xc soon for work out purposes . I had this gearing before and it works rather well for that application

I prefer to climb in slightly higher gears than most because I can't stand the feeling of getting nowhere. I often get up hills a lot quicker than friends with gears because I'm beasting it out whilst they're fiddling with gears trying to make it easy for themselves.

I've never come across hill that you're meant to be able to cycle up and I can't because of gearing.

Long distance and normal hills on urban roads I do rather easily with my current gearing . Add the forest dirt where a harder gear tends to slip and excessively steep angled climbs than it becomes a bit of a different story and the 2:0 ratio is very favored. especially when your 20+ miles into the trail and you have to travel that same 20+ back to the car lol .
