Woods/Dunlop to Presta conversion

Possibly a dumb question but, I picked up a couple of Gazelle bikes that have Dunlop/Woods valves on them. The tubes are toast, can a Presta valve fit the hole or do o nees a rubber thingy in that valve hole?

As far as I know you dont need anything- but why not just be extra careful and feel the inner side of the hole to make sure there are no sharp edges.

woods valves are great-replace-able
being in europe its industry standard.
But presta valves are great on thin tyre bikes.

Thanks for the reply. I know that when you go from schrader to Presta you need a rubber jobbie that reduces the size of the hole. I thought the woods hole is about the same as a schrader?

Woods valve stems are needing schrader sized holes in the rim.
so the grommet of rubber in the hole is a good thing with presta valves

though now P/V tubes like Schwalbe's have a stepped edge ring nut
to center the stem in the larger hole..

though using S/V tubes will do..
