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

Nice thick rubber. Didn’t have a problem with it binding or twisting.

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.

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

I had the entire tube installed in my tire…..when i went to go put air into the tire and tube. The stem popped right off. Not very durable.

This inner tube is thick, 3mm thickness to be exact. Did struggle a little on install but fit very well in tire and wheel. No problems yet but will update!

Only had it on my bike for a month and certainly hadn’t been riding a ton. Came out one morning and tire was completely flat. When we pulled it off found this split in the tube. NOT HAPPY

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.

Great tubes

Very good product very satisfied with it

Best tube I’ve ordered in years. Super thick rubber.
