sent some details on their Erlkönig crank
which we didn't really mention here so far: "This three piece crankset combined the special Fluted
(different wall thickness) CrMo Arms with an extreme reliable hollow CrMo axle
. This axle contains a larger drilling for a larger decrease in weight without a decrease in strength. The 48splined KHEbikes Erlkönig crank is available in two lengths 160mm
(for Flatland) and 175mm (for Street Park and Dirt)."
