RED (pink?) inner tubes??!

[TreaderSteve]

A new one for me - having whipped-off the 'skinny' commuter tyres off the new Merlin I found a pair of red/ pink inner tubes dated 1997 which would fit fatter tyres. They smelt rubbery, seem quite lightweight but I've never come across red inner tubes before!

What are they?! There were a pair of red caps on them, possibly saying Record and patent. One seems alright, one has a snake-bite pair of holes sadly

If you they are even a teeny tiny bit pinched under the tyre bead they willBIGLOUDBANGWITHLITTLEPUFFOFTALC before you notice. That was an expensive afternoon in the 1990s.

Have to keep putting air in them as well.

How much weight did these actually save? I remember them being quite expensive BITD and not being brilliant at keeping the air inside them.
