Onza SA3 MTB Tube

Onza Tires’ inner tubes are available either with a lightweight Presta valve that handles high pressures well or a Schrader valve. The latter, rugged variety is known from cars and allows you to adjust the tire pressure at any gas station. 

Inner tubes are part of the rotating mass, and therefore they should be as lightweight as possible. But they also have to be plenty tough as a flat easily eliminates any gain in time. Additionally, thicker inner tubes are being used during practice. This is why Onza Tires offers its BMX inner tubes in two wall thicknesses, the ones for road bikes in three and the ones for mountain bikes even in four varieties. That way, you have the freedom of choice. So, what would you like?

Features:

  • Thickness: 0.8mm
  • Valve: Presta
  • Weight: 170g (26"), 185g (27.5"), 200g (29")
