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

It appears to be a good inner tube

Heavy duty tube. Ive tried different products from this company and Im completely satisfied with their stuff. Keep making quality products and Ill keep coming back!

Tube didnt hold air out of the box

It is as described I had no problems and the price was a great price for this tube.

If you like thick chicks youll love this 3mm inner tube. Even if youre not into thickness get this tube. Especially if you do it in the dirt. Only 4 on install cuz I have a shallow rim so it was a pain getting the valve through but it should prove worth it. Only 4 on durability cuz Ive only put a couple miles on it. Put some Shinko knobbies on an old BMW R80 ST for around the hood and going to the tavern 30 miles down a dirt/gravel road. Punctured a tubeless tire on the GS on this road so Ill see how this does. Should be fine. Front wheel & on much lighter bike. Unless catastrophic failure occurs Id recommend.

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

Excellent product. Easy to install A+++++

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

Used it front wheel 2002 FXST. LOOKS OF GOOD QUALITY

Looks like nice quality, have not used or installed, bought as a backup, when needed. Would buy again.
