Great tubes. Very thick!
After a long bout of frequent flat tires on the bicycle, I paired these tubes up with Tannus Armour inserts. I shouldn't ever have another flat tire on the bike again.

Only used one so far. Mounted without difficulty, holding air fine. Using in 29 x 2.125 tire.

Disappointed
Despite the rewievs and ratings I'm very disappointed with my experience with these tubes.. not my first time.. followed instructions as alway inflated only 80% of psi and it after 14 miles exploded. Quality is low. Not worth the time buying, waiting and exchanging.

Heavy duty!
Just what I needed. I looked at the sizes and these are very heavy duty and very great price for what you get.
