    Never tried that combo but why fight it? 24/62 combo will fit with no issues and it only increases top speed by a few mph, not enough to notice without a radar gun.

    actually the manufactures sent me a 23T instead of a 24T so it is even smaller!

    you did get a Hardened .8 mod 23T Pinion Gear with 5mm Bore (32 pitch) ?
    Just checking the pitch..

    21/54 is the sweet spot for 2s & 3s

    54 spur &
    21 pinion 2/3s 63.89 mph
    or
    21 pinion 2/2s 42.59 mph

    if you are running 2/2s a 23/54 in not to bad, but really watch temps.

    23 pinion 2/2s 46.65
    or
    23 pinion 2/3s 69.98 a bit over the top..........

    4s = 40 mph

    That looks like a MOD1 pitched pinion IMO.
