Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

that little rubber tube in my puncture repair kit??

can anyone tell me what the deal is with this little bit of rubber tube?

everytime i fix a flat, i wonder what it is, and vow to find out, then forget all about it. fixed a flat today, and decided it really was time to get to the bottom of it.

its listed on the side of the box, but makes no appearance in the instructions.

thanks.

Tire boot? Slip it into a cut/severely punctured tire and it'll maybe get you home, or even last until you can snag a new tire.

It's for repairing Dunlop valves. I remember seeing my uncle repairing Dunlop valves on his bike, when I was a little kid. Don't remember anymore exactly how he did it, but it involved spit.

Yeah- I'm not sure why those are still included in modern kits. You won't be seeing a dunlop valve these days (unless you're buying an old old bike)

Spit is involved but not included in most patch kits.

Try this YouTube video titled, "Woods Valve - aka Dunlop Valve, English Valve and Dutch Valve." It shows the little rubber tube in action. Just in case anyone is still interested in knowing the use.

decade points! woot!

I actually am kinda glad for this resurrection, I love learning about obsolete/regional tech.

I've never gotten a patchkit with a piece of tube in it. monkeyfish's lbs must've been pinching pennies by getting stuff from eastern europe/the middle east.

It's a bit odd really.

Dunlops, with the little tube, were real common when I grew up.
They hold air welll and are easily serviceable.
About the only drawback is a noticeable resistance to inflation airflow.
Here, in Sweden, Dunlops are still common, but a developed model.
The stem and tiny tube has been replaced with a tiny ball valve while retaining the mechanical fit.

Questions about the old Dunlops pop up regularly, but apparently you guys never get the modern Dunlops.

Somebody revived one a few weeks back in the mechanics subforum that was 14+ if I recall correctly.

And of COURSE it was some newbie with literally no self-awareness whatsoever of their ignorance.

I mean really now.

That said, the very best answer of all for this little rubber tube is... drum role please--------

It's a little bit of rubber tube. You never know if you might need a little bit of rubber tube.


I need stuff all the time I never needed before. And I seem to need little rubber tubes more and more these days.


Amazing stuff!
