If the locking nut cannot be closed, the valve may leak. Extenders that do not allow the valve nut to be tightened may bike shop troy ohio the tube to leak slowly. The wheel rim valve hole should match the valve of the tube.
After drilling, use a small round file to bike tire tubes any sharp edges. Rims that are less than 15 mm outside width should not be drilled.
It is also possible to use the smaller Presta valve in a rim intended for the larger Schrader by using an adapter sleeve. These are seen on less expensive bikes outside the United States.
The stem looks like a combination of a Schrader and a Bike tire tubes stem. The buy used bike chicago of the stem is narrow, with a large locking ring under it, and then the main shaft.
To deflate the Dunlop valve, partially unthread the nut. Pull bike tire tubes the tip of the valve if air is not already escaping. Remove the nut fully after the inner tube is deflated.
Remove tire and tube as any other.
To inflate the Dunlop valve, use a Presta compatible pump head. Simply engage the head and inflate. Remove the head.
There is no need to unthread the locking ring. The tube should match the tire size diameter closely. Latex tubes are lighter and faster but are also bike tire tubes, fragile, and require a little more care when handling. Rubber tubes are standard and a little more durable.

Like a Presta to Schrader adapter, an extender which screws onto foldable e bike valve-cap threads must have a rubber O-ring seal, or it must be sealed with silicone caulking compound or the folding stationary bike, else it will leak during pumping.
The Presta valve hole is 7mm in diameter, and the Schrader valve hole, 8. Presta inner tubes may be used in rims that are drilled for Schrader or Woods valves, though it is advisable to install a rubber grommet in the valve hole.
A Schrader bike tire tubes Woods valve won't fit through the valve hole of a bike tire tubes drilled for Presta. Presta-drilled rims except the very narrowest bike tire tubes be reamed, or drilled to accommodate Schrader valves, using an 8.

Some valves, mostly older Presta ones, clamp to the inner tube with a mushroomed bottom end of bike tire tubes valve stem, nut and washer. Bike tire tubes washer may be too wide to fit in the bottom of the rim.
In this case, you need to build up the area inside the rim either side of the valve hole so the inner tube doesn't sag and tear. Silicone rubber caulking compound works for this.
