Rotor Uno cassette
Some components look almost too pretty to use. Rotor’s Uno cassette is one of them, thanks to its (almost) onepiece hollow design. But it’s more than a piece of art. This 11-28t cassette graced the Cyclist scales at just 135g, including the lockring. That’s a saving of at least 40g over Shimano’s top-tier Dura-ace and even more over Campagnolo’s Super Record. Sram’s range-topping 11-speed XG-1190 gets closer at a claimed 151g, but that’s still 16g of extra baggage you’ll have to carry up hills. Your wallet will be a fair bit lighter too.
