Thread: Flybikes Cobra tubes finally

really cool .

I'm curious to see how they would perform for trials.

Didn't Specialized have tubes like this out years ago?

This is exactly what ive been looking for. My chain is cranked on so tight I would need to grind it off.

hmm i will not be useing these.. i can see too much risk of rim damage if you hit inbetween the join spot.

I've used a fair few of them back in the days before i got into trials. They didnt feel any different as the ends overlap a little so there is no "gap". They sure are a lifesaver when you're on a long ride and carry a shifter on you.

Can anyone tell me what the little yellowey coloured tube is for that comes in puncture repair kits?

It's for this type of valve: More precisely for the inserts: Totally outdated, but still part of every repair kit.
