Why does my inner tube have brown liquid inside? Now with internal photo
I've seen that color before. If you are filling from a compressed air tank, make sure the tank has been bled recently. More frequently in humid areas air tanks will get condensation inside. Normal ...

How to stop dealing with flat tires?
You are correct that the type of puncture you're getting is caused by the rim "pinching" the inner tube.
The root cause here is one of the following:
pressure too low (most likely)
You're not ...

How often should I refresh the sealant in tubeless tires?
At minimum, you should replace the sealant every 6 months or so. As you have found, a good tubeless setup will stay inflated well beyond that time, as the latex in the sealant has already sealed any ...

Do I need to refill sealant after puncture?
Pull the valve core and poke a 2mm Allen wrench down to test the fluid level with the valve at the 6 o'clock position with the tire off the ground. You want "some" free liquid. How much depends on the ...

Do tubeless sealants remain a highly viscous liquid or do they form a thin rubber film?
The sealant is a suspension of latex particles. When there is an opening (like a puncture, or a pore in the rubber), the liquid is carried away by the air leaking through the opening, causing the ...

Are presta valve cores universal?
I always save the core out of blown tubes and have never had them not compatible. At the bike store you just see one jar. Might someone come out with non-standard - it could happen.

Will Stans No-Tubes (or other tubless tire sealant) work in a standard tube to prevent leaks?
Are you having problems with flats too frequently for comfort? If not, leave them alone.
If you are, whats causing the flats? Punctures? Too low tire pressure? If its the latter, sealant won't help. ...

Are tubeless tires the solution to frequent flat tires?
I wouldn't go for tubeless as a first attempt to solve the problem. Tubeless might be a good solution for skinny racing bike tyres, which are rather prone to puncturing. But you really shouldn't be ...

How can I tell if my presta valves have removable cores?
Have a close look.
On a presta valve there is a wide threaded part that the lock ring attaches to. And a narrower part with the valve lock nut above it that the cap threads onto.
If the narrow part ...

How to clean sealant stuck in pump head?
You should be able to disassemble the pump head and clean out the blockage manually.
I’d try 70% isopropyl alcohol as a solvent to help remove sealant.

Fixing pinches with latex-based sealant?
Latex based sealants are great at fixing the sort of small holes that you'll get from thorns and glass. If the hole is too big, then all of the sealant will just rush out with the air in your tube. ...

Tubeless tire looses air through weld of rim
If you've only done 100 km on it, its under warranty so take it back.
Sealant may fix it for now, but a weld shouldn't leak air, so its a weak spot on the rim.

How often should I refresh the sealant in tubeless tires?
And probably consider temperatures. In the summer, it’ll frequently be in the 100’s here. I’ve found that it dries up much more quickly when it’s hot.
