skike - Inner Tube 6.25 Inch (SP-KIT 090) black 6.25 inch air tube 6,25 inch with safety valve and protecting cap for all 6,25 inch wheels, long lasting, high load capacity, adjusted to fit all skike models (except Kids v07-S),

Just a lousy product.Skikes are great, tubes are outrageously priced (3 to 4x bike tubes) and they rarely last more than 4 or 5 ski sessions.Tubes are the biggest reason I will be buying new roller skis with solid wheels

Crap. Purchased two. Both suffered dry rot. But nowhere else has 'em. So have to purchase two more and fingers crossed. No happy with purchase at all.
