I've wondered a bit why they just don't make new 8,9,10 speed cassettes with 12-speed cogs and chain. How much narrower would those all be.. and the makers can just sell 1 chain and all the same individual cogs to make up the cassette. That should help with tooling and reducing production lines, no?
