ExtraLite Protect TPU Tube, 650/700x32-52mm, 42mm PV

Aeron TPU ExtraLite Protect is a lightweight TPU inner tube built for riders who want to cut rotating mass without giving up durability. Designed to fit modern wider road, gravel, and 650b/700c setups, it delivers a compact, low-rolling-resistance alternative to traditional butyl tubes in a size range that covers 32–52mm tires.

The tube’s TPU construction is engineered to be extra light and extra strong, with puncture resistance aimed at real-world mixed-surface riding. It also packs down small, making it an easy spare to carry in a saddle bag or pocket.

• TPU ExtraLite Protect construction - low weight with strong, puncture-resistant performance compared to standard tubes
• Low rolling resistance - efficient feel on pavement and hardpack without changing tire choice or pressure strategy
• Compact packed size - easier to carry as a spare than bulkier butyl tubes
• Wide tire compatibility - fits 650b/700c 32–52mm tires for wide road, gravel, and all-road builds
• 42mm Presta valve - practical stem length for many modern rims while keeping weight low
• Up to 80% lighter than comparable butyl tubes - meaningful rotating-weight savings for quicker acceleration and a more responsive ride
