How hard is it to change the inner tube?
Postby peter » Sun Dec 23, 2007 10:29 am
This means I have to visit the LBS to get a new tube and some levers, but should I just ask them to do it? I've read how-to on the web but never done it before, I thought it would be beneficial to be able to do this kind of thing.

Park Tools have a fabulous how-to section on their website here is the section on tyre and inner tube replacement.

One more thing, learn to patch your tubes and be good to the environment.

Spare tube for the first flat and a puncture repair kit for that second flat when you find after pumping the new tube up that the , wire, glass, nail etc is still in the tire or in your hurry to get the tire inflated you have ripped the valve stem away from the tube
For those of us who ride light tires a spare $5 note is handy too. If the sidewall of the tire gets a slice in it that will plug the hole long enough to get you home.
One tip is to mount your tires on the wheels with the tire decal starting at the valve stem this way when you find the puncture on the tube you will know roughly where on the tire you need to look for embedded objects or a hole.
Happy trails

Plus it's expensive to boot! Got caught out on one of my early rides without a pump AND spare tube/patch. Bit the bullet and pulled into a nearby LBS, $20 later...
Reminds me, I need to change my rear tube, and check the tyre/rim while I'm at it. I thought I did that last time, but the new tube went flat within the week, so probably some tiny slowleak-causing nasty in there somewhere...

I always mount my tyres with the valve stem in the middle of the tyre label. A LBS showed me this trick.One tip is to mount your tires on the wheels with the tire decal starting at the valve stem this way when you find the puncture on the tube you will know roughly where on the tire you need to look for embedded objects or a hole.
I also never use the locking rings or caps on my Presta valves.

But with Presta valves any mud just cakes on the outside and is easy to get rid of. The only use I have for the caps is on my spare tubes so that the valve doesn't rub and make a hole.

Hehe... Maybe the fact that I keep those caps on can de-classify me as a weight weenie.s-s-a wrote:But with Presta valves any mud just cakes on the outside and is easy to get rid of. The only use I have for the caps is on my spare tubes so that the valve doesn't rub and make a hole.

The lock nuts are an interesting one - something much blamed for valve failures. I don't use them either, but mainly because I've changed to Michelin tubes which don't have them to start with.

My floor pump has a habit of bending them. Yet again, I am not sure if it's the pump or me that's bending them.europa wrote:The lock nuts are an interesting one - something much blamed for valve failures.

I always run caps on my valves. It's not gluggy mud that's the problem, but muddy water. Centrifugal force in a rotating wheel means that the water goes to the lowest point [deep inside the valve] & even if it dries, the dirt is still in there ready to do it's insideous work the next time a pump is fitted.
I have also seen damaged pins in Presta valves, but if caps are used, it is protected. [I use metal caps on both Presta & Woods valves]
Now that's AUSTRALIAN to the core.

Where do you score metal Presta caps please Kid?

The metal caps were sourced from bike shops all over the SE quarter of NSW back in the early 80's & they had been discontinued & replaced with plastic long before that. I keep a private stash for future use, but keep in mind that they are appropriate for the much earlier bikes that I have.
Sheldon Brown link to valve page.
About the only place I have seen any recently was on eBay.
This is a new tube with a Woods valve & metal cap. This particular one was made for use in a Westwood type rim as the metal flange at the base is shaped to support the valve in the well of this particular rim shape.
Below you will find, left to right a metal presta valve cap, next, a Woods valve without the surgical tubing plus the lock ring & standard metal cap.
On the right is a Woods valve with surgical tubing in place, making it serviceable. If you have ever bought a puncture repair outfit & found these short pieces of tubing in them, then you now know what they're for.
The captive metal cap was just another type.
Now that's AUSTRALIAN to the core.

Pity about the metal cap availability, your fleet deserves them, will suss out ebay.

Well I still use them, so I guess the answer is yes.mikesbytes wrote:Are Woods / Dunlop valves still being used?
EDIT.
OK, I'm not well, bad RTI & bizarre shoulder injury means I am seriously sleep deprived, so I didn't pick up on what I suspect that you mean.
I guess you mean, .... are they still sold new in Australia [or elsewhere]
No, ... new tubes with Woods valves are not readily available through the trade in Australia, although a new [old stock] one shows up in old bike shops on rare occasions. Many of these tubes are made of actual rubber & these eventually deteriorate to the point where they just break up in your hands, but the newer ones made from more modern synthetic materials will last for many years yet.
My last red rubber one [made untill the late 30's] has gone to god & was disposed of thoughtfully about a while ago.
I hear tell that the Woods valves are still being used in some Asian countries, but have no way to verify that.

Others might say that I'm too stupid to get with the times, but I like your version better.
