Is it practical to switch from tubeless to tubes every few weeks?

If you value your time at US\$20 an hour or higher, you’ll find you’ll quickly benefit by just getting a spare set of wheels, leaving the tires permanently mounted, and swapping wheel sets as needed. ...

How to recognize a tubeless tire?

While your question of identifying a tubeless tyre has been answered, I think that might not actually be what you have to worry about. A bike might come with tubeless tyres, but that doesn't mean that ...

Perfectly round holes on new Schwalbe Pro One tire

It is an increasingly common practice for manufacturers to add tire wear indicators, which are little divots like the ones on your tire. Otherwise, there is no objective measure of when to change a ...

Perfectly round holes on new Schwalbe Pro One tire

It’s an intentional wear indicator. There should be “TWI” (Tread Wear Indicator) and a small arrow printed on the sidewall where the dimple is. When the dimple is no longer visible your tread is ...

can I run a tube setup on a tubeless rim without rim tape?

You need rim tape. This is the simplest possible answer. Recall that pre-tubeless, you would need rim tape as well. The tube would expand into the spoke holes and pretty quickly burst. Same story. ...

What air attachment screws onto a Presta valve with the core removed? High volume for seating bead?

Inflator heads with Presta fittings let you do this because they tend to (always?) seal down around the stem, not the core. I don't know any other way. I suppose you could also take a spare Presta ...

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 ...

New tubeless setup: losing air through spoke holes

It seems like there is a problem with the rim tape. The tape should seal the spoke holes without milk. Try cleaning the rim and replacing the tape if it is still loosing pressure.

Does sealant in tubeless tyres slosh around?

Tubeless sealant has the consistency of roughly soy milk. If you take a tubeless wheel and shake it, you should hear the sealant sloshing around (and if you don't, chances are it's time to add sealant)...

White foam around tubeless tires

Modern tubeless bicycle tires require a sealant to be added to the inside of the tire. If a small leak develops the sealant seeps out, meets air, solidifies and seals the leak. I believe this ...

Used tubeless ready tires leaking air (that were used previously with tubes)

Yes, lots of small leaks everywhere typically means you just need more sealant. Tires vary quite a bit in how thin/supple versus thick/strong their casings are. Some tires simply take more sealant ...

Are solid/tubeless tires worth using in Thorny areas?

Both approaches would help, but are very different. A solid tyre is unpunctureable, but the riding properties are much worse. Not only it is slower, but also the adhesion and the feel over uneven ...

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 ...

How much pressure to inflate a tubeless tire so it seats into the rim

TLDR: The pressure you put into the bottle is NOT the pressure to which you inflate the tyre. The pressure drops down as the volume increases when you connect the bottle with the tyre. The final ...

can I run a tube setup on a tubeless rim without rim tape?

Yes, you need rim tape, same as with any tube-only rim. The tube will deform at the spoke holes, any of which can create a puncture. The fact that this is a tubeless-ready rim does not confer any ...
