The Panaracer Purple Lite is a TPU inner tube for 700c road tyres from 23mm to 32mm wide. At just 36g it's less than half the weight of a standard butyl tube, cutting rotating weight and rolling resistance for a livelier feel on the road. It folds down to next to nothing, so a spare disappears into a saddle bag or jersey pocket. Available with 65mm or 85mm Presta valves to suit everything from shallow alloy rims to deep-section carbon. Key Features Thermoplastic polyurethane (TPU) construction - 36g for 700x23-32C Lower rolling resistance than conventional butyl tubes Folds compactly - ideal as a carry-on spare Rim nut and base spacers hold the valve firm for secure pump head fitment and stop rattling Heat-resistant metal valve tip - safe to use with electric pumps and inflators Two-piece Presta valve in 65mm or 85mm lengths Compatibility 700c (622mm) clincher tyres from 23mm to 32mm wide Presta valve rims - choose 65mm for standard to mid-depth rims, 85mm for deep-section rims For wider gravel tyres, see the Purple Lite 700x32-47C version Read Panaracer's fitting instructions before installing What's Included 1 x Panaracer Purple Lite TPU inner tube Rim nut and base spacer Specifications Specification Detail Brand Panaracer Model Purple Lite (Road) Material TPU (thermoplastic polyurethane) Wheel Size 700c (622mm) Tyre Width 23-32mm Valve Type Presta, two-piece Valve Length 65mm or 85mm Valve Material Resin base, metal tip Weight 36g Colours Purple Featherweight TPU for road riders who want a faster-feeling ride and a spare that takes up next to no room.
