How to stop a tube getting damaged in a saddle bag

[scotty]

Regards the goody bag socks, nope,  dont like them, never wear them.

best solution is to take some tubes to your butcher and ask him to vacuum pack them for you.  That way they don't chafe or perish' date=' and they take up less space!

I vacuum pack a tube and a bomb together.

That is a FANTASTIC idea!!!!!!!!!

 

I will do that tomorrow!!!!

I think we need Homer's help here. Hoooooomer! Your phone's ringing.

 

I think all of us have had this problem and it is a difficult one to solve. I doubt an old sock or FL is the solution. The vacuum pack may be, but for a different reason.

 

If you look at the damaged tube, you will notice two types of damage:

 

1) Chafing (which is understandable) and

2) Perishing around all the sharply-bent corners.

 

This perishing seems to happen only where the tube is a little bit under tension. I can't understand that since a tube inside a tyre is under a lot more tension, yet doesn't perish.

 

I am convinced it is a chemical issue and perhaps the vacuum pack removes the offending oxygen which in the presence of tension does the damage.

 

Does anyone have such a damaged tube readily available. Some photos perhaps?

my last one failed on the "tight bends"

I can't find a saddlebag that is aesthetically pleasing and big enough for two tubes and levers and patches, and I don't like having all that stuff in my jersey in case I take a fall (and anyway my pockets are full with mini pump, pepper-spray, phone and cleat covers!).

 

Instead I use a wide-mouthed water bottle which comfortably accommodates all the spare stuff I need. I only need one drinking bottle on a normal ride, so it's not a problem.  There's enough space in the bottle for two tubes and some extra stuff, and it's water (and air) tight. Tip: fasten it to the bottle cage with a ribbon around the narrower neck area to prevent it from bouncing out unexpectedly. Having the saddle clear also allows me to fit a tail light to the seat post without a bag to block it from clear view.

 

Incidentally, I recently found a mini pump (Serfas RP-1) that actually works and achieves reasonable road bike pressures, so I may even dispense with the gas cartridges and fitting for normal rides.

Theonly suggestion I have it to regularly unroll the spare tube and re-roll it in a different way so as to avoid a bend on the same place each time...maybe this will prolong the spare tube's life?
