???? It works in:
- ???? Road bikes (700c / ISO 622)
- ???? Hybrid bikes
- ????‍♂️ Older 27-inch wheels (ISO 630)
⚙️ Key specs (simplified)
-
Material: Butyl rubber
-
Wheel size compatibility:
- 700c (622 mm bead seat diameter)

-
Width range: Designed to stretch across multiple tyre widths
-
Valve types (typical variants):
- Presta (road)
