Continental Race28

These tubes are designed for 700c wheels and are compatible with tires ranging from 20mm to 25mm in width. Please check your tire sidewall to confirm your current tire size falls within this range.

The removable core allows you to easily add tire sealant if you are running a tubeless-ready setup or use valve extenders if you are riding deep-section aerodynamic rims. It adds a layer of versatility that standard fixed-core tubes lack.

The Race28 is built for performance, weighing in at 76g for the 42mm and 60mm valve lengths, and 84g for the 80mm version. This lightweight construction helps reduce rotational mass, which can make your bike feel more responsive during acceleration.

Mold-curing ensures the tube maintains a uniform, consistent roundness throughout its shape. This prevents uneven spots or bulges, leading to a smoother ride quality and more predictable tire pressure management.

They are designed to handle both. While they are light enough for competitive racing, the butyl rubber construction is durable enough to withstand the rigors of daily training rides.
