I didn't say anyone who disagrees is a cycle snob.
I said cycle snobs will bash me for saying it.

Why I love the stuff...

I put the stuff in my tubes as an experiment only a couple of years ago. I'd heard a lot about it, heard the snobs bashing it, and had seen some pretty convincing videos suggesting it was great. So, I wanted to try it out.

It is absurdly messy.

I can't tell a difference in speed or ride with it in or out. Different tires make a huge difference, but I can't tell any difference with sealants.

I use the Slime that is specifically for bikes.

So, several weeks after putting it in my tube, I'd largely forgotten about it except when topping off. I learned pretty quickly that you'd better have the tire rotated so the valve is at the top of the tire when filling it. So, I was riding along, hit something (didn't feel it, just heard a pffft sound that sometimes precedes a flat,) and saw a little streak of green go by on my front tire. As the tire rotated... green... green... darker green... even darker green... almost black... gone...

So, I stopped to check it out, forgetting about the goo in the tube momentarily. Then, it hit me... I'd hit some glass or something, popped a tiny hole in my tube, the slime had leaked out & stopped the leak. I was a few psi lighter at the end of the ride, but never lost enough pressure to stop.


Mind you, I generally buy heavier duty tires, carry a spare, CO2 kit and patches. Since using the Slime, though, I haven't patched a tube or used one of my spares on my bike. Ever. That includes riding on roads, MUPs, sidewalks, occasional dumb off-road excursions and a couple of centuries.

If you took offense to my comment about snobs, it's either because you read my comment in a way I didn't intend, or you're sensitive to the terms snob or sealants. Whatev...

At some point, I may switch to a different sealant, but will never go on a ride without any.
