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

This tube is a back up tube so I have not installed it yet. For the money, the tube looks very durable and the air value looks identical to what I have now. I would buy it again when the time comes.

disappointing...... now I gotta order and wait again....did NOT come with wheel spoke protective rim strip.... MORE MADE IN CHINA CRAP

Great tube. Solid material and solid hardware.

Great value fits great love it

I bought this tube and installed it, will honestly say its the thickest tube Ive ever attempted to run. Installed it and everything was great. Took the bike out for a rip down the dirt and felt accomplished as any person would after putting a tube in. Got back and threw the kickstand down then walked away. Started working on another bike and heard a short brief hissing noise. Went back to the bike and the tire was flat yet again. Removed and found a pin hole next to the valve stem. Had to pull a tube from a different bike and its been fine ever sence

It came with holes all in it not worth it buy from somewhere else

Satisfied customer

I had the entire tube installed in my tire…..when i went to go put air into the tire and tube. The stem popped right off. Not very durable.

I got a flat and had to cha ge the tube it was a pain but thays not the tube fault its holding up well
