Tubeless Conversion Kit, Stem 45mm, Rim Strip 21mm

milKit Tubeless Conversion Kit makes going tubeless simple, clean, and reliable. Designed for riders who want to set up or maintain tubeless tires without the hassle, this system allows sealant to be measured, added, or replaced without fully deflating the tire. The result is easier maintenance, less mess, and more time on the bike.

The unique rubber flap inside the valve prevents sealant from clogging and blocking airflow, a common issue with standard tubeless valves. The included 45mm valves fit most tubeless-ready rims, while the 21mm rim strip offers a secure seal across a wide range of wheel types.

Each kit includes the tools needed to perform a complete tubeless conversion, from initial setup to future sealant refreshes.

• Convert to tubeless easily and maintain tires without full deflation
• Rubber valve flap design prevents clogging and ensures smooth airflow
• Compatible with most tubeless-ready rims for versatile use
• Includes everything needed for setup: (2) valves, measuring/refilling syringe with removable tube, 250ml (8oz) sealant bottle, valve core tool, extra needle, and 10m (11yd) rim tape roll
• 45mm stems and 21mm rim strip provide an optimal fit for many modern wheelsets

For riders who appreciate a clean, efficient tubeless setup, the milKit Tubeless Conversion Kit delivers performance and practicality in one well-designed package.
