Cobra Linear Inner Tubes

[Aushiker]

These tubes look pretty interesting as allow for a tube change without removing the wheel. They got mention on Velomobiles but as they come in 20" they are of course suitable for BMX bikes as well. It would be cool if they extended to other sizes. For those interested the Cobra Linear inner tubes are sold by flybikes.

interesting concept. but i dont see it being much faster to change a tube

Looks like a Spesh Dirt Worm from about 10 years back. Wonder what happened to them?

I'm sure my Dad mentioned using tubes like this in the late forties so you didn't have to remove your back wheel
