Tubeless conversion


Wheelsuck

Recommended Posts

Converted to Tubeless and never been happier-what was I thinking riding UST.

The conversion went ok with Shimano XT Wheels and Racing Ralphs in the back. The problem is the front, Maxxis Ignitors. They loose pressure and dont go totally flat. I have checked the usual stuff valve etc and all is okay.

What could it be?

Submerge the entire wheel in water and look for bubbles. Its a lot easier with tubes though because you can look for punctures by using a bucket or sinkful of water. Having gone tubeless (and 'never being happier' LOL ) you now need a bigger source of water, like a swimming pool. Wink

Just gave Mark Stockton that exact advice this morning to put it in the pool and no for those who worry about the hubs and 'labrador' seals or whatever they called just put sections in at a time don't submerge it!

 

Often times you will find a small leak somewhere that the sealant just doesn't get to during normal riding. Then you can manipulate the wheel to get it to where it is needed. Generally once that seals Bob's your uncle (you may not want that though ....)

Thanks Doug and Big Ben, the problem is that it is not sealing properly? 

 Why does it not go totally Flat, it should go totally flat if it does not seal and mine just looses pressure?

I found it sometimes loses pressure through the sidewalls as the Stans or whatever you  are using only really covers the rolling surface of the wheel rather than the sidewalls. Make sure you have enough sealant in, take the wheel off and rotate it side to side to make sure  the sidewalls are covered.

No worries mate, anything to help a fellow hubber / cyclist.

 

Sounds like the cause of the problem might be that you're tyre isnt sealed properly (as you said). When any tyre is pumped up, the air on the inside tries to escape and is forced out through whatever gaps it can find - in your case a poorly sealed unit. As the air escapes, pressure inside the tyre becomes less and less. Eventually the force of the escaping air is not enough to allow any more air out of the tyre, and you are left with a tyre which which is not quite flat, but is useless to ride on.

im still waiting for an official JB a$$ kicking on the explanation I dished out. Wacko
To me it made absolute sense, now to go and sit in the pool with my wheel.
