• As the title suggests, I'm looking for one, preferably something like 12-21, or 13-24.

    Cash, or I can trade a 6-speed Dura-Ace block in nearly new condition, or a couple of SRAM (Sachs ARIS) 12-21 8-speed indexed blocks which can also be reduced to a 13-21 7-speed by removing the 12t ring.

    Cheers,

    Roddy
