Schwalbe AV4 Tubo Schrader, Nero, 30 x 30 x 30 cm

Bought these for a Brompton, originally with standard Brompton tyres, but more recently switched to Schwalbe Marathons.I quite like like the smaller cross-section, as makes slightly easier to fit and means they take up very little space if you need to carry a couple. Quality seems good with the few I've bought so far. Possibly lose about 5-10psi a week in my experience, riding around 125km per week.Update: You can actually get two of these tubes in the box they come in. Shame they don't sell them like that. I wouldn't necessarily keep them in the box, but when I've got a mixture of stuff in my bag, I figure the box at least stops silly mishaps.Update2: Recently switched to Schwalbe Kojak tyres, and can confirm that these still fit great, still only lose 5-10psi per week. I did have some other tube in my rear, but the valve on this failed when I was replacing the tyres. Not had a puncture for a while while running on Marathons, so could just be me being out of practice, but actually, showed me that I definitely prefer the valves on these to the other tube I had. Plus, when I'm not with the T-bag, I can still easily get a couple in my saddlebag, along with tools, etc.
