BBB Cycling BTI-211 TPU Gravel

Ultra-Lightweight Speed. Next-Gen Puncture Defense.

The engineering hallmark of the BBB Cycling TPU Tube is its high-density TPU construction. Despite weighing up to 70% less than standard butyl inner tubes, TPU is inherently tougher and more tear-resistant, offering superior defense against punctures and pinch flats. The ultra-thin wall structure minimizes internal friction against the tire casing, delivering a fast, supple ride feel that rivals tubeless setups while holding air pressure far more consistently than latex options.

Why the BBB TPU Tube Belongs in Your Setup:

• Massive Weight Savings: Slashes up to 100g per wheel of rotating mass compared to standard butyl tubes, delivering faster acceleration and easier climbing.

• Compact Saddle Bag Fit: Rolls down into an incredibly small footprint, freeing up valuable space in your jersey pockets, frame bags, or repair kits.

• Enhanced Puncture & Pinch-Flat Resistance: Thermoplastic polyurethane provides exceptional tensile strength, making it harder for thorns, glass, and sharp rim strikes to pierce the tube.

• Lower Rolling Resistance: Thin, supple material conforms easily to tire casing flex, saving energy and smoothing out road and trail chatter.

• Durable Reinforced Valve Stem: Features a sturdy valve body designed to prevent air leaks and resist stem shear under hard braking.

• 100% Recyclable Material: Made from eco-conscious TPU material that can be recycled at the end of its lifespan.

Technical Specifications:

• Material: Thermoplastic Polyurethane (TPU)

• Wheel Size Options: 700c

• Valve Type: Presta (Alloy stem with removable core)

• Weight Range: ~60g–75g

• Brake Compatibility: Disc Brake Only (TPU tubes are sensitive to extreme rim-brake heat)

The Alegro Perspective: TPU tubes have completely changed the game for emergency repair kits and weight-conscious builds. Carrying two traditional butyl tubes takes up your entire saddle bag; carrying two BBB TPU tubes takes up no more room than a couple of energy gels. Plus, dropping nearly half a pound of rotational mass off your wheelset is one of the cheapest, most noticeable performance upgrades you can make. It’s the perfect middle ground: tubeless-like rolling efficiency without the mess of liquid sealant.
