Swap your standard rubber tubes for this ultralight TPU upgrade and feel the difference immediately. The thinner profile reduces rotating mass, giving you sharper acceleration and less fatigue on long climbs. Designed specifically for mountain biking, it grips tight within 26 or 27.5-inch tires ranging from 1.5 to 1.95 inches wide. You will appreciate how quickly it seats and maintains consistent pressure over roots and rough descents.

A 45 millimeter Schrader valve keeps inflation straightforward on the trail. The flexible polymer construction resists punctures and handles repeated bending without cracking. This change means fewer roadside stops and more continuous riding time when you push through technical sections.

Benefits & Tips

  • Safe Inflation: Always use a manual hand pump rather than high-speed compressors to protect the delicate TPU walls.
  • Quick Setup: Fold the valve inward and pump gently until the tube rounds out below 0.5 bar before seating it fully.
  • Heat Management: Remember that every three-degree temperature jump raises internal pressure by one percent, so check gauges before hot ascents.

Product Specifications

  • Primary Material: High-grade TPU polymer for superior stretch recovery and abrasion resistance.
  • Compatible Sizes: Fits 26 x 1.5-1.95 inch and 27.5 x 1.5-1.95 inch mountain bike rims.
  • Valve Type: Standard Schrader (FV) measuring 45 millimeters in length.
  • Tare Weight: Approximately 42 grams for the 26-inch model and 45 grams for the 27.5-inch version.
  • Maximum Pressure: Rated to hold up to 5 bar or 72 PSI safely.

1 × Gustavu TPU Mountain Bike Inner Tube

Warnings

Never inflate this tube completely before mounting it, as rapid expansion causes permanent damage. Keep unmounted tubes dry and always store tires deflated to roughly 1 bar if exposed to direct sunlight or storage temperatures exceeding 60°C. Watch ambient heat carefully during summer rides, as black asphalt roads can spike internal pressure and force sidewalls past their limits.
