My affection for options made Rotor’s 12x cassette catch my eye at Sea Otter 2019. It leads in several categories, being lighter (323g), less expensive (365 USD), and able to fit a conventional Shimano HG driver body. Remember the one everyone used before SRAM’s XD driver showed up? As a result it has an 11t smallest cog, but it compensates by going to 52 for the bottom end so you can use a larger chainring and preserve your range.

The Rotor cassette also scores points for sweet engineering and stunning presentation. It’s the sort of component you want to put on your bike because it appears to be hewn from Mithril by elves with skill and precision that puts both humans and machines to shame. That may be taking it a little deep, but it’s an accurate reflection of my affection for finely crafted bike parts in general, and the Rotor cassette specifically.
