Review on 🔧 High-Quality Bell 26-Inch Universal Inner Tube: Optimal Width Fit Range 1-3/8-Inch, Black by Eddy Borghesi

I bought these tubes to better fit my Michelin Run'r road tires on my 1987 mountain bike. I alternate between fatter trail tires and street tires depending on where I ride. I didn't want thicker tunes in street tires because the tubes are too thick and will flex on their own as street tire bounce rates increase. These tubes fit better, but one of the two tubes I bought still folds on its own because its 26" diameter is slightly larger. They fit better than thicker tunes in general and the tubes are cheap so they are good value for money.
