Hade redan lagt i ny slang (Continental) men som hade en ventil som vare sig passade min gamla postcykel eller jag lyckades pumpa däcket genom mer än en gång så har nu tvingats kassera två nya contislangar samt ett nytt däck från Biltema som var märkt 26" men visade sig vara 24" och köpt nytt här och ännu så länge är jag fullt nöjd!

問題なく6バール空気を入れることが出来ました。

La inflé con una bomba manual hasta que reventó ( sin que el neumático llegara a estar realmente duro al tacto con la mano).Tampoco en la caja pone la talla que promete el desplegable de Amazon ( 26 x 1 1/8 )

Considerando mi grado de discapacidad psicomotriz severa, he sido capaz de montarla. Y por ahora (sorprendentemente) resiste y no ha dado ningún problema. No es la más barata del mercado, pero contento con la experiencia de compra.

I'm not sure who's to blame for this, but if you want the 1.75 in. Schrader-valve tube, double-check once you click "order". When I did it, the subsequent order information said "26X1.25/ 1-5/8"... not that I double checked it until I already got exactly that in the mail. I alerted the vendor, they very graciously provided me with a refund (even though it's tough to say whether it's an Amazon error or a vendor error). So this may stop being a problem soon, but double-check that. As for the actual product, it's a high quality tube. As evidence: I was desperate and really needed to be up and rolling again, so I went ahead and used them (it didn't help that I didn't actually notice the issue until they were already installed). The size differential from 1.675 to 1.75 isn't too large, and these are high quality tubes, so I've been able to roll w/o problems for around 100 miles (on- and off-road) w/o problems. So kudos to Schwalbe on their product, but still... double-check that size.
