MICHELIN - 38637 - Inner Tube
Michelin's 38637 Inner Tube is built with its signature Airstop construction, placing the splice directly opposite the valve to keep the tube balanced rather than lopsided. The overlap splice used here is inherently stronger than the butt splice found in many other tubes, and Michelin's Airstop line has long been the choice of riders who simply want the best inner tube available rather than the cheapest.
Features
- Splice is always placed opposite the valve, which helps to provide a more balanced tube
- Features an overlap splice which is stronger than the butt splice used in most others
- Michelin Airstop tubes are used by those who want the very best
