Inner tubes - wtf???

[Joe24]

how does anyone need so many tubes?

Got 3 Specilized ones at the moment. 2 for the fixed when its built and one spare for the fixed. Also got one spare for the geared.
So far, not had a puncture other then when i have been hand-fisted and ripped the valve off. I was using Kendas for ages aswell, now on Conti Ultra-gatorskins.
I like the Specilized ones, but only because they are £1 and they arent bad quality.

You mean why?

The problem is when a sharp object enters my tyre it becomes a more bumpy ride.

The idea is to put another inner tube in which is able to hold it's gas.(oooer)
