Pirelli ANGEL™ SmarTUBE X TPU Inner Tube
The Pirelli ANGEL™ SmarTUBE X is a reinforced TPU inner tube developed specifically for daily riding, fast urban commuting, and endurance city cycling. Designed to prioritise comfort, durability, and reliability, it delivers exceptional puncture protection while remaining significantly lighter and more compact than a traditional butyl inner tube.
Frequently stocked by trusted bike shops, the Angel SmarTUBE X is ideal for riders who rely on their bike every day.
TPU Construction with Enhanced Protection
The Angel SmarTUBE X is made from TPU (Thermoplastic Polyurethane), a high‑performance material that offers greater strength and elasticity than standard butyl rubber. Compared with conventional inner tubes, TPU allows up to 70 percent weight reduction while improving resistance to cuts and abrasion.
To further enhance durability, the Angel SmarTUBE X is three times thicker than a standard SmarTUBE, giving riders added confidence when navigating rough city streets, debris, potholes, and inconsistent road surfaces.
Built for Comfort and Reliability in the City
Urban riding places unique demands on equipment. Frequent stops, variable road quality, and higher puncture risk all require dependable components. The thicker TPU formulation of the Angel SmarTUBE X helps absorb small impacts and reduces the likelihood of sudden flats, making it well suited for:
- Daily commuting
- Fitness riding
- Endurance road use
- Fast city and suburban cycling
This focus on reliability makes it a common recommendation from Brisbane bicycle mechanics for riders who want fewer interruptions during their weekly rides.
Lightweight and Compact for Practical Riding
Despite its added protection, the Angel SmarTUBE X maintains excellent portability. It takes up around 50 percent less space than an equivalent butyl inner tube, making it easy to carry as a spare in a bag or pocket while keeping overall bike weight down.
For commuters and recreational riders alike, this combination of compact size and durability offers a practical upgrade with no downside.
Wide Compatibility for Modern Bikes
The Angel SmarTUBE X is compatible with disc and rim brake wheelsets, making it suitable for a broad range of modern and classic road, commuter, and hybrid bikes. A black Presta valve provides reliable air retention and a clean, unobtrusive finish.
