Latex Tube Crinkle
Moderator: robbosmans
Hey,
Does anyone know why my latex tubes did this?
Thought I would test some brand new latex tubes on my race tyres before my first race on them.
Ride went well, front tyre was surprisingly grippy but kind of noisy. (not used to corsas).
Switched back to my normal/training GP4000SII today and the latex tubes looked like this (photo attached)
Can anyone explain this?

Are you using smooth rim tape? The tube stretches a bit more there. Not a problem, I run latex in 4 wheelsets and all my tubes look like this.

Do you use talc powder ? It seem not. It's essential with latex tube: talc on the tube and inside the tire.

The tube has been folded onto itself. not a real issue, but please use talcum powder like the previous poster said. If you want to get your latex tubes out of your horrible GP4000's in a month or so, you might rip them to shreds as they have got stuck to the vulcanized rubber.
If you want to see 'meh' content of me and my bike you can follow my life in pictures here!'Tape was made to wrap your GF's gifts, NOT hold a freakin tire on.'
Before install, I'm putting every tube into a plastic bag with talc and shake until the tube is fully covered.
In my opinion, this contributes to the above effect since it will slip even more on a smooth tubeless type rim tape.

Another thing is to put air in the tube before mounting it. Install the opposite end of the tube (from the valve) first and make sure it's not twisted.
This method together with abundant use of powder helps to seat the tube straight and evenly.
I'm crazy with the talcum powder. I put it on the rim bed, inside the tires and on the tube.

I think it is due to the latex nature. It looks to me like this section of tube is a bit thinner. And after streaching it doesn't come back to it's oryginal shape, if you know what I mean...
Vittoria tubes are notorious for getting bigger and bigger with the time they are used.
Every time I'm changing tyres with these tubes and reinstalling them I wish I had few inches bigger wheels to accommodate extra streched tube
As I remember all my latex tubes (five different brands) had more or less these kind of wrinkles. As my memory serves me well I have never installed latex tube without a talcum powder.

Latex on DA c24 wheels with separate rim tape, heaps of talc, still get these wrinkles.
Latex on Fulcrum Zeros with a solid rim bed and no tape, loads of talc, no wrinkles,
both with Veloflex Corsa tires.
I wondered whether its movement in the rim tape causing it?

Thanks, I do everything you say here but I could be more liberal with the talcum powder. Is baby powder the same thing?alcatraz wrote: ↑Fri Jun 22, 2018 2:57 pmAnother thing is to put air in the tube before mounting it.

Or it may be more the movement of the tube across the spoke holes causing little digging.jasjas wrote: ↑Fri Jun 22, 2018 9:28 pmLatex on DA c24 wheels with separate rim tape, heaps of talc, still get these wrinkles.

I'll add that to my list of things to buy. As long as it's safe to use the tubes as I am (with extra powder)
Michelin is the thickest of all the latex tubes.
