Tubeless Tips Series: Inflation valves, rims, spokes
Filed Under Articles
This is the 4th post in our series of tubeless tire tips. If you’ve missed one of the earlier part, here they are: Part 1, Part 2, and Part 3.
Removing and replacing the inflation valve from a tubeless rim
To remove the inflation valve
Loosen the nut that retains the valve. Push the valve body up through the rim. Keep track of the valve and nut so that they are easy to find when you use them again.
To replace the inflation valve
Clean the area where the grommet will seat on the rim strip and the grommet itself. If you used any caulking or sealant on the valve previously make sure you remove it thoroughly. Automotive brake cleaner is usually good for cleaning the rim area since it does not leave a residue.
Make sure the hole in the rim strip aligns with the hole in the rim.
Push the valve through the rim strip and seat the grommet in the central groove in the rim strip.
Tighten the retaining nut by hand only. You might have to remove it on the trail if you have a flat.
Truing the rim
If you don’t need to replace spokes you can true the rim with standard tools without removing the tire or rim strip. If the nipples are binding you will need to lubricate the spoke threads or nipple seat. Use a light oil on these sparingly.
Replacing spokes
The spokes can be replaced in the same way that you would replace them in a traditional wheel.
Make sure the spoke is the right length. If the spoke is too long it might contact the rim strip and puncture it.
Spokes on the Mavic UST wheelsets are usually only dealer replaceable or require a send off to the factory.
