Just received two more forks back. This time both of them got the insert. One was from a bike ordered in November 2011, the other in August 2012. They may have abandoned the x-ray process and just started to put inserts into all forks, but we need more data before having any degree of certainty about it. We've been weighing forks with and without inserts, unfortunately some are different lengths, and we never weighed the same fork before and after the insert, but we estimate the extra weight of the insert to be about 10-15 grams, so no big deal. Forks that get the insert also come back with a new compression plug included since the internal diameter is greatly reduced.
