What Is It
The Ryder TPU Inner Tube 700x35–50C is a thermoplastic polyurethane (TPU) bicycle inner tube designed for 700c wheels running wider tyres (35mm to 50mm).
Unlike traditional butyl tubes, TPU tubes are much lighter, more compact, and more puncture resistant, making them popular for road, gravel, and commuter riders who want lower weight and better efficiency.
The FV 48mm RV refers to:
- FV = Presta (French valve)
- 48mm = valve length
- RV = removable valve core / standard valve type variant (depending on packaging)
Key Features
- Ultra-light TPU construction (lighter than standard butyl tubes)
- Fits 700x35 to 700x50 tyres (wide gravel/road compatibility)
- Compact folded size (great as a spare tube)
- Better puncture resistance than standard rubber tubes
- 48mm Presta valve for most standard rims
- Low rolling weight for improved ride efficiency
- Ideal for tubeless backup setups
