What about tubes and tubeless?

Clik Hi-Flow Cores for Presta stems can replace removable Presta cores in compatible inner tubes and tubeless valve stems. You do not automatically need a whole new stem.

For inner tubes, including TPU tubes, confirm that the Presta core is removable. A fixed, nonremovable core cannot be upgraded by swapping the core alone.

For tubeless wheels, you can use a compatible existing stem with a removable Presta core or install a complete Clik tubeless valve set. Choose the stem and rim gasket for your wheel setup.

The core is designed for most Presta stems; do not assume every third-party stem is identical. If the core type or fit is unclear, send the tube or stem model and a close-up photo before attempting conversion.
