SuperLite Race AL TPU Tube, 27.5/29x1.7-2.5", 42mm PV

Aeron TPU SuperLite Race AL TPU Tube is a performance-focused TPU inner tube built for riders who want to cut rotating weight and pack a smaller spare without giving up everyday usability. Designed for modern trail and XC wheel sizes, it fits 27.5" and 29er tires from 1.7–2.5", with a 42mm Presta valve suited to most rims. With an aluminum CNC-machined, anodized valve stem and a removable valve core, it’s also easy to service and compatible with common inflation setups.

• TPU construction - exceptionally low tube weight for riders prioritizing efficiency and a more race-oriented setup
• Compact spare size - takes up less space in a pocket or pack than a typical butyl tube
• 27.5"/29er fit range - covers a wide span of tire widths (1.7–2.5") for XC to trail use
• 42mm Presta valve - a practical length for many MTB rim depths without excess valve protrusion
• CNC-machined aluminum valve stem - precise, durable stem with an anodized finish
• Interchangeable valve core - supports electronic pumps, screw-on pump heads, and valve extenders for flexible inflation and easier maintenance
• Weight comparison - up to 80% lighter than comparable butyl tubes
