To be fair, the Miche cranks are the best out of the whole Miche set.
My hubs threaded, lockring notches got chewed up, the track nuts bascially melted when I tried to take one off.
Yet my cranks have taken an absolute battering and are still running fine.
until you try to remove them and the cheesethreads strip too.
which results in chopping the spider arms off with a boltcutter and sawing them off
