Kelly - Just in case I sounded dismissive - there's nothing 'wrong' with low gearing, your knees will thank you for it. And if you can ride at 1-2 MPH up those grades it sounds like you've got the right stuff happening. A lot of the weaving or unsteadiness has to do with your balance fore and aft

I briefly ran a sub 18" gear way back in the days of 28 tooth big cogs, using a Mountain Tamer Quad; I think the low was 18 or even 16 X 28. It was pretty useless off road, mostly because by the time you had managed to curse the chain onto the sub-granny, you had already fallen over. But even the 2

I regularly see short pitches that hit 12%, and a couple of roads our club rides during the summer hit 15 - 17%. On those rides I'm generally riding my lightweight go-fast with a 34/29 low gear and no more load than a couple of tubes and a Clif bar. Anything much past 10% is a bit of a slog, but

I'm expectin to be dragging my 180 # butt and 35# of bike plus day gear - no overnight, it's a SAGged ride. Noodling with numbers I think an 18 to 20 gear would let me spin at 4 to 5 mph, but that'll be at my peak power. It's said to be 1/2 mile, so that could take worst case 10 minutes. Doesn't

I believe I am as I live in the foothills of Mt. Rainier...I think if I only had a 40-50 pound load I would be fine with my present gearing. When I say "touring load" I mean around my middle...due to age, sedentary life, too many carbs, bad sleep habits, too much stress. Not giving up thoug

I agree with Steve - you can only ride so slow. Balance and steering quirkiness was my experience with riding a 24x34 (18.3") up steep stuff at around 4.25 MPH. Charlie: if you are concerned with your knees, as we all should after the age of ~55, the ole "heel/toe" gear might be safer and besides

If rested and on short rides I'd probably never use it but I carry a full "touring load" all the time and in spite of my efforts to reduce by riding, I only drop 20 pounds at the peak of the riding season. Grants recent writing clued me into the compensation eating that I know I do so I am trying
