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

Fit just like it was supposed to. Seems durable. Pinched it pretty good at install. Was worried I put a hole in it. Nope thank goodness it was as thick as it is.

Great price fast shipping, seems to work just as it should

Would buy again.

Great tube. Solid material and solid hardware.

I always put a little air in the tube before installing, this tube never made it to the install. I was excited to try it thinking I could get more than 1 tire change out of it. Had a hole in it straight out of the package, guess I should stick with name brands

Arrived early and was not disappointed. Tube was heavy duty and actually had to let it set out in the sunlight to warm it up to be able to work it into the new tire. No issues with installation. Has held pressure for over a week now without any loss of psi. Perfect fit for my 1996 Honda Shadow 1100 ACE. Would definitely recommend

Great tubes

Was very impressed with how thick the tube was. Ive got about a thousand miles on it now with no problems whatsoever doing a severe amount of off-road riding. I am a larger guy about 300 lb with an Enduro and its not having any trouble with weight or abuse.

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

Easy to install and fit perfectly
