$4.20

These are now my GOTO inners. Cheap enough to have a few in the shed, plus a spare one on the bike (commuter, Cannondale).
Does what it says on the tin. Great price from trusted source
Not used it yet, it's in the rucksack just in case.
There seem to be a lot of cheap and nasty inner tubes about. These are great.
As stated above, Decathlon finally have this in Presta valve.
Saved me a lot of money taking to the shop! Did this at home myself with my Dad. Just takes a little effort that’s all. Job perfect!
Thanks
Good product, does what it’s designed for. Cheap but effective.
