Alta 700C Bike Inner Tube – 48mm Presta Valve, Fits 18c/23c/25c Tires

Need a spare tube for the road bike?

This Alta inner tube is a solid choice.

It's a standard 700C size that fits tires from 18c right up to 25c.

The valve is a 48mm Presta (that's the skinny French one) with a threaded stem, so it locks in place on your deep-section rims.

It's made of good ol' rubber, weighs next to nothing at 0.3lbs, and comes brand new in the package.

Just swap it in and you're back on the road.

Valve core is non-removable, so keep that in mind, but for a standard tube, it does the job perfectly.
