I have a 2018 FIXIE Inc. Betty Leeds.
These are the sizes of the tyres:
Reifen vorne Marke: Kenda Typ: K-193 Größe: 28 Zoll Reifenbreite: 28 mm
(Tire front Brand: Kenda Type: K-193 Size: 28 inches Tire width: 28 mm)
and I am looking for inner-tubes here: https://www.bike-discount.de/
Unfortunately, I did not see the description of the inner-tyres in the web-site. Which one should I buy?
