BBB BTI-165 CoreCap Valve Cap 2-piece Set in Purple

Season:2026

Brand:BBB

Say goodbye to the hassle of bending or breaking fragile Presta cores with this robust design, which ensures easy installation without unscrewing or adapters. Experience consistent airflow with up to 300% improvement, perfect for effortless tyre pressure adjustments across all riding styles, including tubeless setups. Built for durability, the CoreCap valve withstands regular use and makes maintenance a breeze, greatly enhancing your cycling experience.

CoreCap was designed with one clear goal: to deliver a better user experience than traditional bike valves. Suitable for both inner tubes and tubeless systems, CoreCap solves long-standing issues related to fragility, restricted airflow, and maintenance. No more bent valve cores and no tubeless sealant blocking airflow. The innovative internal construction maximizes airflow and makes adjusting tyre pressure easier than ever. This means faster inflation, more precise pressure adjustment, and effortless tubeless setup. In many cases, the tyre bead will seat without the need for a compressor.

BBB's CoreCap offers true universal compatibility. Thanks to its design, the valve works with standard Schrader (AV) pump heads, allowing you to inflate your tyres anywhere, including at a gas station, with no adapters required. This compatibility works both ways: the CoreCap Valve Caps Upgrade Set can be mounted on any fully threaded Presta valve with a removable core, including valves on inner tubes.

Features:

  • Winner of the iF Design Award 2026
  • Easily replaces traditional Presta valve cores without the need for adapters
  • Compatible with all fully threaded Presta valves with removable valve cores, including those on inner tubes
  • Delivers up to 300% more airflow compared to traditional valves
