Default How to Slime a Presta valve tube

I have just ran into the problem of getting Slime into a tube that has a Presta valve.

This, is how it is done! :-)

the valve stem is much smaller in diameter than our customary Schrader valve, so it is less of a weakness when the hole is drilled in a bicycle rim.
...Especially those skinny racing rims!

I don't care for them, yet I have no need for them...
I suppose I would use them if I was pedalling road racing bicycles.

Good to know, thanks RC. I'm down to one last Presta valve tubed tire in my garage, everything else has Schrader valves. It won't be long before I switch out that last one, either... I hate fiddling around with Presta valves. The bike shop I won't go to anymore put them on my wife's bike when she dropped it in for a check and tune up a couple of years ago (just after she got it), and insisted they were better valves. They might make sense on a high-end racing bike or some thing, but on a MTB with the rim already having a Schrader size hole for the valve stem it made no sense, just added a couple of bucks per tire expense (the true reason for installing them I suspect).

All excellent info! I keep an airhorn mounted in a flashlight holder in case of ferrel/loose dogs.

Weld it solid. They are known to fail due to the weak internal construction and welding is the most common, fastest, cheapest fix.

If you use 29" tires, the cheapest and most readily-available replacement tubes are ones are from Walmart and they have Presta valves. And even if you buy online, Presta-valve 29" tubes are more common.

looked a bit online - seems if a guy comes to my shop with a flat & has one of these, he'll leave with the same flat as my old compressor won't fit it : (
