Instead...likely in an effort to conserve cost, Campy revised their procedure to no longer offer the short chain section for 11s chains such that their revised pin design can now be used in 'non virgin' holes where a previous peened rivet was pushed through?
If the latter is the case, wouldn't this agree with Rob's assertion, i.e. that the virgin hole sizing for 11s chain is indeed identical to the hole size left when pushing a peened rivet out?
Yes, the procedure is not the same, if the chain is broken and rejoined.
All it means is the flared end of the new joining pin provides enough strength to allow it's use in a hole that's had a pin pushed through it, whereas the old style that relies ONLY on a interference fit with hole will not. It would be stupid for Campy to put a zip tie through a pair of plates and insist that it be used for the initial chain joining, if that pair of plates had a peened pin pushed through it.
