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.

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

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

Works as intended

seems okay so far, made a difference on riding...

Good quality and price

Tube didnt hold air out of the box

Just got mine put in and was absolutely impressed with these tubes chonkiness, these bad boys are beefy compared to a standard tube. Shipped quick and was not much if any more difficult than installing a standard tube. Would definitely recommend either soapy water or talcum powder to help get it in and inflate properly but honestly youd have to try to twist this beef cake of a tube while putting it in.

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