Miche Primato Hub Bearings

Trying to order some replacement bearings as mine seem to have self-imploded. Do we think these might work?

Don't know whether to order the C3 version or not... Do hubs count as high velocity/high temperature?

Clearance: For each of these options you have the choice of a standard fit bearing or a C3 fit bearing, C3 have additional internal radial clearance and will feel loose when fitted until running at speed. They are commonly used in high speed and high temperature environments. If the bearing you are replacing is not stamped with C3 then you should purchase standard fit, as a rule you should replace like with like.
