Excess Ultra Light Tubes — Presta Valve 40mm

Overview

The Excess Bluetech Ultra Lite (ULT) is a lightweight inner tube engineered from thermoplastic polyurethane (TPU) for BMX racing. At approximately one-third the weight of standard rubber lite tubes, these tubes minimize rotational mass while maintaining puncture resistance and low rolling resistance. The 40mm Presta valve with removable core suits standard BMX racing applications.

Key Features

• Thermoplastic polyurethane (TPU) construction — High-grade polymer compound developed for performance; significantly lighter than natural or butyl rubber while maintaining durability
• Ultra-lightweight design — Reduces rotational weight on wheels, improving acceleration and responsiveness
• Puncture-resistant material — TPU formulation resists pinch flats and punctures despite minimal wall thickness
• Low rolling resistance — Optimized material properties reduce friction with tire and rim, improving speed and efficiency
• 40mm alloy Presta valve — Standard BMX racing valve; removable valve core enables sealant injection for tubeless conversion
• Smoked clear TPU finish — Durable, transparent appearance shows valve position and tube condition
• Patented welding and valve design — German engineering ensures consistent seams and valve reliability
• 100% recyclable material — TPU can be recycled at end of life
