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

Definitely heavy duty. Better quality than stock.

Good quality and price

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

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 have not rode my bike yet but tire and tube balanced with no weights and the tube weighs quite a bit which I like. I wish they made one that fit my rear tire.

Great value fits great love it

Excellent quality. Nice and thick. Fit my stock 1999 Triumph Thunderbird front tyre perfect!

Was just installed, durability is still to be rated in time.

Heavy duty tube for off road bike. Works great!

They hold up OK. Not the greatest but for the price its good. I had recently bought one. Im almost positive it had a hole in it when it was delivered but I cant prove it because I had already installed it in the tire before I aired it up.
