Continental ContiTech Light Tube

Yes, this tube is designed for 700c wheels and is compatible with tire widths ranging from 20mm to 25mm.

The removable core allows you to easily add tire sealant if you are running a setup that requires it, or to attach valve extenders if you are using deep-section aerodynamic rims.

The Light version uses a thinner material profile to reduce rotational weight and rolling resistance, which can make your bike feel slightly more responsive during acceleration and climbing.

While it is optimized for racing performance, the durable butyl compound makes it reliable enough for everyday road riding, provided you maintain proper tire pressure.

Yes, the threaded stem helps secure the tube in place when using a pump head, ensuring a stable connection and preventing the valve from pushing into the rim while you inflate.
