Product Description

MEROCA Ultralight TPU Road Bike Inner Tube – Fast, Light, and Built to Last

Upgrade your road bike setup with the MEROCA Ultralight TPU Inner Tube, designed for riders who care about speed, weight, reliability, and packability. Made from advanced thermoplastic polyurethane (TPU) material, this tube offers excellent elasticity, strong puncture resistance, and significantly lower weight than traditional rubber inner tubes.
Available in 700C x 23–32C with Presta/French valve options, it is suitable for road bikes, gravel bikes, endurance riding, commuting, racing, and long-distance spare tube use.

Key Features

Advanced TPU Material

The inner tube is made from high-quality TPU elastic material, offering better stretch, abrasion resistance, and puncture protection than many standard rubber tubes. It helps reduce flats from small cuts and sharp objects while maintaining a smooth rolling feel.

Ultralight Performance

Thanks to TPU technology, the tube is extremely lightweight, helping reduce rotating weight for quicker acceleration and easier climbing. Depending on valve length, the tube weighs only:
  • F/V 45L: 35.6g
  • F/V 65L: 38.4g
  • F/V 85L: 39g

Presta Valve for Better Air Retention

Equipped with a Presta/French valve, this inner tube provides strong air tightness and stable pressure retention. It is ideal for modern road bikes, performance wheels, and deep-section rims.

Compact and Easy to Carry

The TPU tube rolls down smaller than a traditional rubber tube, making it perfect as a pocket-sized spare. It fits easily into a jersey pocket, saddlebag, or frame bag without taking up unnecessary space.

All-Season Durability

With good heat and cold resistance, this TPU inner tube performs well in different riding conditions. Whether you ride in hot summer weather or colder seasons, it remains flexible and reliable.

Low Rolling Resistance

The soft and elastic TPU structure reduces friction between the tube, tire, and rim. This creates a smoother ride and helps improve pedaling efficiency.

⚠️ Before installation, slightly inflate the tube to check for leaks, then deflate it before fitting.
