Sunlite Thorn Resistant Tube 700x35-43 Schrader

Thorn-resistant tubes are ordinary butyl tubes made with a much thicker casing, and Sunlite's are the ones bike shops have stocked for decades. The 700x35-43 Schrader size fits most 700c commuter and hybrid e-bikes. The thick wall stops the short thorns and wire that cause most commuter flats, at the cost of weight and a slightly dead ride feel. They pair well with a puncture-resistant tire for riders who refuse to fix flats on the roadside. If your rim is drilled for Presta, Sunlite sells the same tube with a Presta valve.

Best for: 700c commuter e-bikes in thorn and glass country · Riders who want belt-and-suspenders flat protection · Heavier riders who pinch-flat thin tubes
