Weighing a mere 69g each, Kenda’s Ultralight tubes would be my choice over Latex variants if I was trying to shave every last gram from my bike. So if you’re a nimble, lightweight racer, these could be a good investment but the heavier and more puncture prone amongst us should look elsewhere.
Weighing a whopping 460g, these are ultra heavy- duty tubes for riders looking for the last word in durability and in both wide section 700c or 26 they’ve never once let me down in several thousand mixed terrain miles.
Made from 4.6mm thick butyl, they’re four times thicker than your bog standard tube and feel every bit the proverbial builder’s hose. Aboard my four season’s fixer with big 38mm rubber they’ve laughed at flints, thorns and riding through shards of glass may have nicked the tyres but it’s never touched the tubes.
