Continental TPU Tube - Presta Valve

The Continental TPU Tube – Presta Valve is a cutting-edge, lightweight inner tube constructed from thermoplastic polyurethane (TPU) in a unique, airtight seven-layer design. Engineered for road, gravel, and MTB riders focused on performance and compact storage, it's durable, low rolling resistance, and remarkably light and compact.

Continental TPU Tube Specs at a Glance

• Material & Construction: Seven micrometer-thick sealed TPU layers for maximum air retention and strength
• Weight & Compactness: Weighs approximately 35 g—far lighter and more compressible than traditional butyl tubes
• Valve: Presta valve, internally threaded with a slightly conical base to better seat in rim holes and accommodate valve extenders or replacement cores
• Valve Core: Removable, facilitating the use of CO₂ inflators or valve extenders
• Compatibility: Designed exclusively for disc brake wheels; not compatible with rim brakes due to heat sensitivity

Design & Performance Benefits

1. Exceptional Air Retention: The seven-layer TPU structure offers superior airtightness without sacrificing performance
2. Ultra-Light & Packable: Minimal weight and compact storage size make it ideal for competitive riders or minimalist packing
3. Smooth Fit & Stability: The conical valve base supports secure seating in high-profile rims, reducing valve stem movement
4. Easy to Service: Includes a repair kit, and the removable core allows easy servicing or adapter use

Mounting & Usage Notes

• Do not use with rim brakes—heat buildup may cause sudden pressure loss
• Avoid over-inflating during installation—keep pressure under 0.3 bar until fully mounted to prevent overstretching
• Ensure proper rim tape coverage to avoid punctures from spoke holes
• Match tire size precisely; do not reuse in smaller tires to prevent damage

Final Take

The Continental TPU Tube – Presta Valve delivers cutting-edge performance for the discerning cyclist. With ultralight weight, excellent air retention, and compact size, it’s an outstanding choice for race-day setups and streamlined spares. Just be mindful of the disc-brake-only design and follow installation guidelines for reliable performance.
