Maybe I am missing something obvious, but here is a pic of the inside of my Veloflex Corsa.

Some companies by products from another and rebrand them. Others have products manufactured by other companies for them.

I know that much, but I didn't know about a Veloflex-Schwalbe cooperation. They still have made in Italy on them.

Hi,

What doe the outside say?

Ciao,

No doubt. Those are not Schwalbes. The folded over "open tubular" design does not fit Schwalbes MO. Plus, last time I checked, Schwalbe didn't use cotton casings.

That exact text is written on Schwalbe Inner tubes, though. Some kind of transfer effect?

Mr. Muncher might be on to something. 18-28 isn't exactly a common tire size.

Haha! Think we have solved the mystery....

Only used them with vredenstein latex tubes.. Maybe the shop have mounted them before? But I remember they arrived sealed in the box. The transfer makes a lot of sense though.

but if it were a transfer from a tube, would it not be mirrored?

Indeed , it'd be mirrored

15 is the number for their racing innertube,
Indeed, it should be mirrored.
Maybe Schwalbe and Veloflex are made in the same factory?

Last time I checked open tubular = clincher with added marketing.

Right it suddenly all makes sense, sorry for the fuss

I mirrored the pic before I upload it just to be easier for reading. And I remember I got a flat while I was my way to the tourmalet and bought a schwalbe tube of a local shop. It was a very hot day (probably around 35+) so I assume in the descent the wheels got hot and thats how the mark got there.

Now I probably need to go to a doctor and check the memory gaps

An open tubular as apposed to a clincher would be a tire with a high thread count cotton casing, with a glued on tread (so as not to effect the casing's feel) that would normally be sewn into a tubular. that has instead had it's edges folded around a bead to be used on clincher wheels. Clinchers tend to be lower thread count, nylon cased tires that have everything vulcanized together. And the two ride very differently.
