Compatibility, Size and Fit
References to cruiser, gravel and hybrid bicycles do not establish fit for every bicycle in those categories. Check the size marked on your current tire, wheel compatibility and frame clearance before selecting this set.
What Is Included
The set contains two 26 x 2.10 tires, two 26 x 1.75/2.125 inner tubes with AV 32 mm Schrader valves, and two tire levers.
Safe Use and Important Precautions
Before installation, check the tire bead wire for severe bending that prevents it from returning to shape, and look for exposed metal. Check the rim for burrs before fitting a tire. If an inner tube bursts after installation, inspect the tire for damage, including a broken bead wire, exposed metal or broken cord fabric, before replacing the tube. Follow the instructions for your bicycle and tire when installing and inflating.
The tires may feel soft when unfolded. If you fold or roll them again, do so gently and do not force them.
Before You Decide
Confirm the 26 x 2.10 (54-559) size, tire clearance and compatibility with the included Schrader tubes. Check that the stated pressure range suits your setup and that the two tires, two tubes and two levers match what you need.
