ConsStandard postage cost for small parts annoying.
ProsAs above
Seldom fails to be able to supply those difficult to source items, very often at a sensible price.
Usually my first call and go to supplier.

What can you say. Its an inner tube. Made of butyl rubber, its black and does what it says. Probably more durable than most (other than Airstops (but they are hard to find in Brompton size)) and comes with a well thought out valve retainer. Natty clear plastic dustcap.

Do they do this with a black valve?

If not available in black valve, can you suggest a presta 40mm tube with a black valve? Thanks
Sorry, we have not seen anything with a black presta valve!

Would this be suitable for 18" x 1.5 Schwalbe tyres?

Hi, I live in New Zealand, and I've just bought a Birdy Classic, that runs 18" wheels, and am looking for inner tubes, possibly new tyres too.
Do you guys post to New Zealand?
Also do you stock any parts for the Birdy Classic (2003 model).
You need SJS Cycles part number : 3833 and we ship worldwide.

Do your schwalbe inner tubes come in boxes?

The box really helps when checking which tube fits which bike when you've got several!

Yes these tubes are boxed.

The tube for 18 x1.25 Tires?
