GAADI - Makes bicycle tube changing a piece of cake
GAADI produces innovative butyl bicycle tubes with two ends, which is why it is not necessary to remove the tube in the case of a puncture. A real pleasure for Holland bike owners. The "open" tubes are available for wheels sizes from 26 to 28 (29) inches, with Schrader, Dunlop or Presta valve. To simplify the insertion of the tube, the valve is located in the first third of the tube length.
