BBB CoreCap - Black

BBB CoreCap BTI-165 Valve Upgrade Kit - Black

The BBB CoreCap - Black reinvents the traditional Presta valve to offer a more robust, practical, and significantly improved solution. Designed for road, gravel, mountain, and urban cyclists, this upgrade kit allows for easy replacement of compatible Presta valve caps and cores to significantly improve airflow and ease of inflation.

Winner of the prestigious iF Design Award 2026, the CoreCap stands out as a true innovation for both tubeless systems and inner tubes.

A new generation of Presta valves

Say goodbye to fragile Presta valves that bend, flex, or break. The CoreCap was designed to eliminate the common hassles associated with inflation and maintenance.

• robust and durable solution
• no adapter needed
• quick and easy installation
• Compatible with threaded Presta valves with removable core

Up to 300% more airflow

Thanks to its optimized internal design, the CoreCap significantly improves airflow compared to a conventional Presta valve.

Inflation becomes faster, smoother and more precise, which also facilitates tubeless mounting without the need for a compressor.

• up to 300% more throughput
• faster inflation
• more precise pressure adjustment
• tubeless mounting made easy

Compatible with inner tubes and tubeless tires

The CoreCap kit is suitable for both tubed and tubeless setups.

It allows for easy modernization of an existing valve without changing the entire system.

• tubeless compatible
• compatible with inner tubes
• road, gravel, mountain biking, urban
• also suitable for electric bikes

Universal compatibility

The major advantage of the CoreCap lies in its compatibility with standard Schrader (AV) pump heads, without an adapter.

This allows you to inflate your tires at home, in a workshop, or directly at a service station.

• compatible with Schrader / AV pumps
• compatible with standard bicycle pumps
• No adapter needed
• simplified daily use

A solution designed for all bicycles

The CoreCap is suitable for a wide variety of uses and wheel sizes, from city bikes to 29-inch mountain bikes.

• road
• gravel
• Mountain biking
• urban bike
• e-bike

Awarded the iF Design Award 2026

The CoreCap received the prestigious iF Design Award 2026 in Germany, recognizing its innovation and ability to radically simplify bicycle tire inflation.

Selected from over 10,000 applications, it perfectly illustrates a modern approach to bicycle components.
