Oh Snap! (Schlumpf Axle)

I believe there have been some normal KH hub axles broken. But the Schlumpf has a hole through the axle for the shifting mechanism, so it is probably at least a little bit weaker than the stock KH.

Doesn’t the bolt hole in a normal axle go in as far as where that one broke? Perhaps not. Are the crank bolts on the Schlumpf axle larger diameter than the normal KH ones? If so, that would make the axle slightly weaker. AFAIK there are two common ISIS crank bolt sizes - 12mm and 15mm. I think the normal KH hubs use 12mm.

Anyway, commiserations to the OP - I’d be really annoyed with myself if that was mine.
