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

As good as any tube you can buy. Course rubber dry rots but these are fresh... I want all the protec i can get from hitting the asphalt in point 1 seconds.

Im rolling again so far so good only time will tell its holding up 4 now

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

There tunes. They work.

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

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

Very well made..I have my buddy using them on his bike now too..so much easier too get the tire back on the wheel without pinching the tube

Seems to be a very good tube for the price. It is 3mm thick vs standard 1.6mm

Perfect for front tire 2020 hawk 250 DLX EFI

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