PIVOTRAX 90/90-21 or 80/100-21 (3.00 X 21) Heavy Duty Motorcycle Tube - 3mm Thick - TR4

This is a spare tube for my motorcycle trips, cant really give you much info at this time, but it appears to be satisfactory.

worked as it should

This tire is very good. Second one I have had on my DR350. It works perfectly for adventure biking and reliable in the woods/dirt.great tire

Great value and so far holding up well to the abuse with lower tire pressures.

Exactly what I needed no lies in between I ask for innertube and that’s exactly what I got

Quality of the tubes are 1st class. Shipping was so slow, that I thought the were sent by wagon.

Great quality good price would buy again

Replaced front tube in my 1990 DR250S with 90/90-21 front tire. Excellent quality.

Muy Bueno

Delivery was great. Overall I’m very happy with them.
