I, of course, did change to a larger ring on my hardtail, but there are clearance issues with a full suspension. On most full suspension bikes, at least mine, a 34T chainring is the largest you can go, which might be enough,
But I wasn't asking how to fix the problem, just how useful a gear that low was.
What many of you are missing is the age consideration. What someone can and would do at 30 isn't the same as what they can and would do at 70. The possibility of falling and getting injured is a much bigger consideration when you get old. I'm picturing pedaling like mad, on a really steep climb, and fighting to keep upright. I'd probably get off and walk.

Plenty of people have replied that they've been happy riding steep uphills with a gear equal to or lower than your low gear. So there's your answer.

If you can't go any larger than 34 for your chainring, swap the cassette for one more narrowly spaced. Problem solved.

Or even more simply: leave everything as is and don't use that sprocket. The bike I ride most often still has a triple crankset. I've used the small ring maybe five times in the last five years.

On the other hand, I should probably get rid of my fire extinguisher since my house hasn't yet caught fire and I don't expect it ever will.

No. And those of us have been riding since 1x12 was a thing which is approximately 2015 and a lot of us, like myself, have lower gearing such as 30 x 52 or 28 x 52

All you have to do is switch to higher gear. This isn't that difficult. The low gearing you are complaining about is useful for when the bike is actually ridden for it's intended use...Off road on single track trails.

Like I said, I wasn't looking for a solution to a problem. I can find my own solutions. All your suggestions, about possible solutions, were already extremely obvious to me, but thanks anyway.
I was simply asking if others found a 32X51 gear to be too low to be of use.
Just curious if it was just me or others thought it was crazy low too
.
I already looked into changing the cassette on the full suspension bike. Would have liked a 9X45, but not compatible with my set-up. But I might get a 10X45.
I think 32X51 is lower than I can use but I need to make sure that 32X45 is low enough. I need to do some more riding on the full suspension before making a decision.

I'm not denying that useful gearing is useful, I'm denying that, for me and maybe not for you, a 32X51 isn't useful for me. I can't see ever using it.
On that note, getting a cassette, with a low gear you only use once or twice a year, maybe isn't the wisest decision.

I've had hundreds of cassettes during my life.
I've been riding since before there were cassettes. You could buy and change individual cogs. I've built up my own cog sets numerous times.
My theory on cassettes is that, yes, you should take the maximum high and low, you might ever need, into consideration, but another consideration is what gears you are going to use frequently. Using road bike gearing as an example, getting a 12X32 cassette when you'll only use the 12T or 32T cogs a few times a year, maybe isn't the way to go. You might be better off getting a 13X28 and just accepting that there will be a few times when the 13 and 28 aren't enough.

Yes. It's probably more annoying to many of us old guys that there are far fewer cassettes available with a 13-tooth small sprocket than there were 15 years ago.

Certainly more annoying than having a bail-out gear at the other end of the cassette that gets used only once in a while.

The common 11-tooth small sprocket is mostly useful for pedaling slowly downhill, for those who like to pedal on steep descents for some mysterious reason.

From what you are telling us you are a long time roadie, (which is fine), however road gearing will be different from MTB gearing for the sheer fact the surfaces ridden on are going to be quite different. Like extremely different. Climbing a hill on a smooth surface vs. a rocky rooted muddy surface is not the same at all so having some lower gearing is quite helpful. You may not use that gear all the time and nobody is forcing you to do so but having it is quite helpful. Sure back in the early days it was more touring/road gearing as they were still developing MTB so it is what existed but now we can see where everyone else is at and it feels like you are trying to deny that and aren't understanding the reasoning and why even the pros have lower gearing.

It's definitely you. A lot of us included myself have even much lower gearing and it's not a problem. But that lower gearing is never used on the flats or mild hills. It's for grinding up a steep and long hill.

Get it out on a trail and you will appreciate that lower gearing.

I guess you haven't really told us...But where are you planning to ride this Full Suspension mountain bike? If it's not on Single Track trails then you bought the wrong tool for the job.

Downhill is for coasting.

I use the 11 tooth during a sprint to the finish line in a race. Stand up and mash it!!

Not exactly what the OP is asking, but there is some debate among MTB-ers about what ultralow granny gears are good for. While they're great for slow grinding up relatively non-technical steep sections, once you hit tech and need a sharp pedal punch to get over an obstacle the low gear often doesn't work. Paradoxically when the going gets harder a harder gear is required.

So when I swapped from my old 32T for a 28T chainring it made some of the 25-30% (non-technical) sections of trail around here much more doable for me, but it didn't really help my tech climbing at all.
