what one person needs to win a race,
what I need to ride the range of terrain I ride,
and what other people claim is all you need,
and what people tell me I need (when they don’t even know what I ride)…
are 4 entirely different things.
i have 21 single speeds presently, with 2 clever mechanical devices for selecting which of those 21 speeds to use and when, even if some are effectively duplicated.
edit: heck, even 1×1 32:16 is more than you need, what with a rider almost on the podium at the last DH worlds with no chain, and then Gwin winning a world cup round with no chain.
make it simple, bin the cassette, both mechs, shifters and have an even less cluttered bar (not that 840mm bars would be what I call “cluttered” or full), and ride a dandy horse! no mech to get twisted round cassette, no mech to spack spokes, not rear hanger to snap, no KMC vs Sram chain fanboi-ism… and races are winnable!
