This is a 41ish question but I didn't want to have to read the "they suck" and "I weigh 225#, jump curbs and have no problems" responses. Is it risky to ride tubeless tires with no sealant?
I just ordered a set of 6700 tubeless wheels from our sponsor shop because a couple of people on my team had raced with them last season and were happy. Racing isn't an issue, being out on my own in the middle of nowhere is.

my main question is how consequential is the terrain you're riding? speeds on the road are often higher than MTB speeds and you have less rubber between you and the road should the tire go flat. sealant can (duh) seal a puncture (it at least has a chance) or possibly slow the rate down enough for you to come to a controlled stop.
running without sealant will mean an increased chance of flatting and riding directly on your rim. i won't argue how much the odds increase, but they do increase. if you're riding flat terrain, probably not a big deal. if you ride mountain passes, it's a bigger deal.
as for the corrosion issue, generally trust the manufacturer to have the best information. this used to be a bigger deal with old sealants, but more recently sealants have come out that do not use ammonia, which i think was the source of the problem. generally, caffe latex or similar is considered to not be a problem with aluminum rims. maybe sk shimano if there are any types of sealant that they feel are ok, or if it is a blanket statement.
if the latter, it's probably a case of shimano being uber-conservative, as they do with chain wrap & capacity for derailleurs.
hope this helps.
yep. they are basically valve stems with an enlarged rubber base that mates well with the rim. you just push the whole thing toward the inside of the rim and the stem will pop out. insert new tube, inflate & win.

My wife and I are have been in the process of building a multi purpose space. Her side will be her art studio, mine is a study and meditation room. Local artist is making an abstract stone Buddha for the boulder, and Grumpy is working on a desk.
Pics are mostly of my space.

now that's all wonderful and stuff, but we are only interested in seeing the pain cave for your rollers
Anyway, it was a pretty sweet car and did nothing to convince me I don't need one. Even my wife is behind me buying one. So, we are going to go through tax season - I converted some 401(k) rollovers to Roth IRAs this year and need to pay the taxes on them - and see where we are in a few months.
$2.5k should get you some quality stuff that will last you ages. As they say, never skimp on shoes and haircuts. Getting a suit that fits is also important. Whatever you do, just don't get 3-button suits (unless if you are 6'5") or black suits.

I showed my wife the picture of CDR's cats and mentioned he had alot of cats. She said "I only count 7 cats." and reminded me how many we have and have had.
Rescuing a pregnant cat causes you to lose count quickly. Luckily, half are indoor/outdoor and are in just to eat or sleep when it's really cold.

Missus is a CPA and worked out the various permutations. Based on that she converted. I wanted to copy her but failed.
We have 8 - we haven't had a chance to get all of them at once. It's rare enough that we got the 7 in one area. We adopted out 4 kittens, 1 adult, and there are 3 fixed but still feral cats at the store where I used to work. I thought we were down to two at the store - life expectancy for a feral cat is 2-3 years so not surprising as it's been 4+ years - but someone there saw the third only a month or so ago.

assuming you can get the tire to seal without using sealant, then there is no reason why the tire can't be ridden w/o sealant (or extra sealant as a prophylactic measure).
my main question is how consequential is the terrain you're riding? speeds on the road are often higher than MTB speeds and you have less rubber between you and the road should the tire go flat. sealant can (duh) seal a puncture (it at least has a chance) or possibly slow the rate down enough for you to come to a controlled stop.
running without sealant will mean an increased chance of flatting and riding directly on your rim. i won't argue how much the odds increase, but they do increase. if you're riding flat terrain, probably not a big deal. if you ride mountain passes, it's a bigger deal.
as for the corrosion issue, generally trust the manufacturer to have the best information. this used to be a bigger deal with old sealants, but more recently sealants have come out that do not use ammonia, which i think was the source of the problem. generally, caffe latex or similar is considered to not be a problem with aluminum rims. maybe sk shimano if there are any types of sealant that they feel are ok, or if it is a blanket statement.
if the latter, it's probably a case of shimano being uber-conservative, as they do with chain wrap & capacity for derailleurs.
hope this helps.
yep. they are basically valve stems with an enlarged rubber base that mates well with the rim. you just push the whole thing toward the inside of the rim and the stem will pop out. insert new tube, inflate & win.

Shimano says "We do not recommend that you use general purpose alkaline puncture repair agents as they may cause the rims to corrode and allow air leaks to occur." The Shimano rep who was at the shop at the time just said not to use liquid sealant to keep from damaging the rims. I didn't know enough about them to ask whether he meant everything or if the newer latex sealants would be okay.
