Replacement inner tubes for both Knobbly and Street tires.

It's a good idea to purchase spare inner tubes for your SUPER73, as fat tyred bikes are more prone to punctures than traditional sized tyres.

This Tube is suitable for the SG2 and RX Models.

Dimension: 20"x4/4.5"
Provided as a single tube
Schrader valve

*Recommended 18-20 PSI may vary dependent on riding terrain and weight of rider.
