Bought a RF 35mm offset rim.
2 annoying pin holes in the side of the rim are for what ?
Are they holes for gases to escape as the rim is pressed ?
Annoying because they are close to the edge of the tape and separately have to sealed with silicon.
speed hole for sureView attachment 381124
Drain hole?
Those ones are drain holes, yes, to let water out of the rim. But they don't go into the rim bed so wouldn't interfere with taping.Drain hole?
Funny though air comes out maybe via the valve ?Those ones are drain holes, yes, to let water out of the rim. But they don't go into the rim bed so wouldn't interfere with taping.
Possibly, are those holes pictured above the ones you're referring to? Or are there others in the actual rim bed (you mentioned being close to the tape/having to silicone them)? Certainly possible that air is leaking from the valve - can be relatively easy to not quite seat the valve fully in the hole or have the tape interfere with the seal, or sometimes the valve core can be a little loose in the stem... Are you losing air from the tyre or just curious about the holes?Funny though air comes out maybe via the valve ?
Once the air escapes the rim bed it is in the body of the rim and may then appear to come from the drain holes or spoke holes.Yeah I always find setting up new tubeless an epic.
Once it is sealed it is fine thereafter.
I always put silicon in the spoke holes , carefully tape the rim , the valve always leaks for me initially despite putting silicon in the hole , adding an o ring or plumbers tape and doing the valve up tightly .
This time air was hissing out of the drain holes in the picture so it must be coming via the valve.
I have put in plenty of Stans sealant and rotate the wheel.
