Bumping this as a bit of a public health warning.
My first day back in work today, 29 of the 69 miche primato cranksets we have fitted to bikes are cracked.
None of the smallest size of bike have the crack but from 52cm up they are there and fairly evenly spread, not like just one or two in the smaller sizes then lots on the bigger bikes so I don’t think you could say the crack was symptomatic of the bike being overloaded.
We don’t really keep track of when a bike is involved in a crash so it’s entirely possible and perhaps even probable (?) that every bike that has a cracked crankset has been crashed at some point but none of them have been used anywhere other than an indoor velodrome.
