Alvas Inner Tube (TPU)

$37.00 CAD
Quantity

The TPU Inner Tube is designed for riders chasing lower weight, faster rolling, and improved ride efficiency. Built from advanced thermoplastic polyurethane, it delivers a significant weight reduction over traditional butyl tubes while maintaining consistent air retention and durability.

With a compact profile and an 85mm valve stem, it’s ideal for deep-section wheels and modern road or gravel setups.

Available in two thickness options to suit different priorities, from maximum durability to ultra-lightweight performance.


Option 1: Reinforced TPU – 0.35mm

A more robust TPU construction for riders who want added puncture resistance without sacrificing much weight.

Specs

  • Wheel Size: 700c

  • Tyre Width Compatibility: 23–32mm

  • Weight: 49g

  • Valve Length: 85mm

  • Wall Thickness: 0.35mm

  • Use Case: Training, gravel, endurance riding


Option 2: Ultralight TPU – 0.20mm

An ultra-light option built for speed-focused riders and race-day setups, delivering the lowest possible rotating weight.

Specs

  • Wheel Size: 700c

  • Tyre Width Compatibility: 23–32mm

  • Weight: 32g

  • Valve Length: 85mm

  • Wall Thickness: 0.20mm

  • Use Case: Racing, fast road rides, weight-critical builds


Why It Stands Out

  • Dramatically lighter than traditional butyl tubes

  • Reduced rolling resistance for a faster ride feel

  • Compact and easy to carry as a spare

  • Long valve length suited for deep carbon rims
