EVO Bicycle Tube - 18" x 1.75-2.125 | 35mm Schrader Valve

Is the EVO 18" Schrader Tube the Right Spare for Your Bike?

The EVO 18" Bicycle Tube is a dependable spare built for kids' bikes and smaller-wheeled setups that use 18-inch wheels with 1.75 to 2.125-inch tires. The 0.9mm wall thickness strikes the balance between packability and puncture resistance that riders need from a backup tube, not so thin it's fragile and not so thick it adds unnecessary weight to your saddlebag. The 35mm Schrader valve is the same standard valve found on car tires, meaning any gas station pump or floor pump with a Schrader head gets you rolling again fast.

EVO tubes are manufactured to consistent dimensional tolerances so the tube seats cleanly in the tire without bunching or pinching during installation. This is the size you want stocked in your garage for kids' bikes, youth mountain bikes, or any smaller-wheeled ride that runs Schrader valves. Keep one in your bag on rides and one on the shelf at home . at this price, there's no reason to get caught short. Compatible with 18 x 1.75 to 2.125-inch tires with Schrader valve rims.
