SuperLite Race AL TPU Tube, 650/700 x 32-52mm, 42mm PV

Aeron TPU SuperLite Race AL TPU Tube is a performance-focused inner tube built to reduce rotating weight and pack down smaller than traditional butyl—ideal for riders chasing faster acceleration, easier spares storage, and a more race-ready setup. Sized for 650/700 x 32–52mm tires and finished with a 42mm Presta valve, it fits a wide range of modern road, all-road, and gravel wheel/tire combinations.

• TPU construction - Low bulk and low weight for a lighter rolling setup and a compact spare in the pocket or saddle bag
• Broad fit range (650/700 x 32–52mm) - One tube covers many popular high-volume road and gravel tire sizes
• 42mm Presta valve - Practical length for many rims without excessive valve height
• CNC-machined anodized aluminum valve stem - Precise, durable valve hardware with a clean finish
• Interchangeable valve core - Simplifies service and makes it compatible with many valve extenders
• Pump and accessory compatibility - Works with electronic pumps, screw-on pump heads, and valve extenders for easier inflation across different setups
• Weight comparison - Manufacturer states up to 80% lighter than comparable butyl tubes
