Tubeless Tyres -"saying the same things about tubeless tyres over and over again" Hippy read the first f**king post

Hey!

Can you pm me with details?

The tyre has to come off if you're using anchovies anyway, unless you want to risk stabbing your rim tape

Insert the tool at an angle.

The obvious answer is the best. Why make life hard for yourself by removing the tyre.

I've been converting some non tubeless rims used with schwalbe g one successfully.
The thing is the rims are Schrader, while the valve I used were presta. Last Friday the valve decided to go awol, I suspect from moving around to much when pumped using hand pumps.

As I got some 26in inners with Schrader valves, I tried cutting them and using it.
The problem is while when using the presta, the tyres pumped up and the bead locks.
It does not happen with the Schrader, anyone knows why?

Cheers,

Probably either the seal around the non-tubeless valve isn't good enough or the schrader valve doesn't let air in quick enough.

As in the air seeps between the excess inner tube?
Maybe I'll have better luck cutting them closer to the valve then?

Already tried using air compressor, so this should not be a problem.

Right going to pull the trigger and give it go, as even the LBS said I should rather than them. Buying the tyres, what would be decent valves?

MilKit valves sound good

Obviously a little expensive but being able to replace sealant easily is a bonus

I bought some the other week - to go tubeless on a second bike - but haven't fitted them yet

Whatever's cheapest and works. Have these on my mtb. Come with a spare valve core and a tool to boot.

Effetto Mariposa valves are good, as are Reynolds or whoever makes them.
I had some generic no brand ones that i binned.

You want a good seal/ seat in the rim and quality removable cores.

And obviously long enough for your rim depth

I just cut em out of busted inner tubes...

doin it rite

Get some lifeline wiggle valves, or whatever is cheap

I second the Effetos, they're excellent quality, and they come with a little adapter for the rim shape, and there's no risk of pulling them through the valve hole either.

I have just bought a cheapie set of 650b rims which are tubeless ready.. can anyone recommend some 650b tubeless CX tyres that would fit a frame with clearance for 28mm 700c?

There's no set rule to tell how much you'll be able to fit. Mount the rims, get a Vernier and check the clearance where the tire would be, that would give you an idea.
You may end with fairly smaller wheels than the 700c equivalent, make sure the bottom bracket doesn't end too close to the tarmac

I haven't received the wheels yet, but measuring 320mm from the axle the there is 48mm rear and 51mm front clearance.. would 2" tyres fit? or maybe need something a bit smaller?

maybe need something a bit smaller?

Definitely need something smaller. The official minimum clearance is 4mm all round (EN14781, 4.10.2), which suggests 40mm true width is where you should be aiming.

Surely not, 2" is about 50mm and you need a bit of clearance.

Sounds stupid, but does a 2" tyre actually measure 2".. will wait till they come and have a rough fit.. my frame has max clearance of 28mm on 700c..

does a 2" tyre actually measure 2"

Some do, some are more, some are less.

Any recommendations for something around the 40mm mark?

tubeless ready.. can anyone recommend some 650b tubeless CX

You're fishing in a small pond if you want 40-584 tubeless CX, the serious CX tyres tend to stick to UCI 33mm max, and the bigger 27.5 tyres mostly start at 2 inches. Maxxis Rambler and Schwalbe G-One All Round are the ones which immediately leap out as jumping through all your hoops.

I suppose 33mm might be ok, I would just be wary of the overall diameter dropping and my BB and cranks coming too close to the ground.

I had seen the G-ones..

About to attempt a ghetto tubeless setup. and have a couple things I'm not sure of,

1 - I was planning on using a valve cut from a tube. Should I be putting the valve in the rim then applying gorilla tape and them piercing through the tape or tape the rim then push the valve through the tape?

2 - My rim is drilled for presta but I don't have any presta tubes with removable cores in my stash. Will a presta without the core removed allow enough air in to seat the tyre? I could bring it all to work and use the airline rather than a track pump.
