First Look: ToPeak Adds to the List of Alt-Valves with New TurboFlow Adapters

"Similar to some other Presta valve replacements that we've seen, such as the Clik Valve, the BBB CoreCap, and the Capless Speed Valve, ToPeak's TurboFlow is sold as an adapter that attaches to your existing valve stems. On ToPeak's global website, there are complete valve kits with TurboFlow heads, coming in 45, 60, and 80mm lengths. At present, ToPeak's U.S. site lists only the TurboFlow Adapter kit, sold with or without the brand's RapidHead combo."

"ToPeak's new valves appear to have a fairly simple design. The body of the TurboFlow adapter threads onto the outside of your existing Presta valve stem (assuming it has external threads). The valve itself is a fairly wide, hollow tube with a stopper at the bottom, inside the housing. The valve has a lock nut at its tip that holds the stopper closed when tightened and allows the valve to open (slide up and down) when loosened."

"When depressed, either with your finger or the force of air pumped into the valve, the larger diameter valve opening and simple, open design reportedly allow for three times the airflow of Presta valves. This is intended to make pressure adjustments or installing tubeless tires quicker and easier, and it should also reduce the likelihood and frequency of sealant clogging."

Many brands have introduced alternative valves and adapters to replace or augment traditional Presta valves. ToPeak's TurboFlow is offered as an external-thread adapter that attaches to existing Presta stems and is available in multiple lengths and kit configurations. The TurboFlow uses a wide, hollow tube with an internal stopper and a tip-mounted lock nut that closes under tire pressure and opens when loosened. The larger diameter opening and simple design reportedly allow up to three times the airflow of Presta valves, aiming to speed pressure adjustments, simplify tubeless installations, and reduce sealant-clogging frequency. The adapters appear visually chunky.
