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

Good product nice and thick did not put a hole in with my spoons!

Good quality and the rubber is really thick! Super beefy tube. I like it! I was surprised when I pulled it out of the box. I dont think Ive every installed a tube this heavy duty before.

Really bad my tube was not good the box was all f up. Not good dont buy here an my tube was pop.

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

Just as described

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

I ordered the heavy duty tubes for my BMW R1200GS (21 front wheel) and they fit correctly and where easy to mount. The tubes are also packed in a plastic bag inside the carton for easy and not stinky transportation if used for a spare tube.

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

Great heavy thick rubber inner tube for motorcycles. Fast ship.

Great tube. Solid material and solid hardware.
