I am confused. I know they have sizing ranges for French/presta tubes but do not for other tubes. Why is that? Also, I ordered a bike tube that was advertised as 650 x 23c/26c. What I received was a 650 x 25c. It doesn’t state that it is compatible with sizing ranges. Will this work for my 650 x 23c tire? Your assistance with helping me understand the sizing would be appreciated.
Thank you

Bike tube sizing is messy and rarely critical.
While too big is usually more of an issue than too small, I would happily try a 25C tube in a 23C tire. If it looks like the new tube can go in w/o creasing, install and ride.

Thank you so much for your assistance. It is a tube that I had planned to just have as a backup for a long trip. I think I will swap it out to make sure that it will work before we get out to ride. I appreciate your assistance.
