Default Shimano chains - rivet reuse?


Martin wrote:
The other day the mechanic at my local bike shop rejoined my Shimano 10
speed Ultegra chain reusing two rivets. Looking at the link under a
jeweler's magnifying glass I can clearly see that the peening on the
rivets is missing and I can see the countersinking in the plates around
the rivets.

The mechanic is very experienced, very well respected and services many
bikes in a busy shop.


BUT he made a serious mistake. BAD idea for any shimano chain, REALLY
bad idea for the 10s chain. He is asking for a broken chain, on a chain
that is known for breaking even when connected properly.


It looks like the rivets have been inserted to the
correct depth. Nevertheless the contact area between rivets and plate is
substantially less than it should be and the peeening that would prevent
the rivet moving is absent.

I am interested in readers' opinions and experience regarding the safety
and durability of this repair job. Do many people reuse rivets? Any
experiences of reused rivets working well? or failing?

Many thanks

Martin
