absoluteBlack Aether Carbon Ultra-Light Tubeless Valves Size:30-55mm rim Ambient Kinetic Technology (ReAKT) enablesETHER takes a completely different approach to tubeless valve design by removing the traditional valve core entirely. No tiny core. No tiny airflow path. Nothing to clog. Its simplified two part architecture creates a more direct airflow path for easier inflation, improved tubeless setup and reduced maintenance over time. Instead of CNC machined aluminium, we use long carbon fiber polymer composite injection. This allows for significantly lower
