Again, never had a problem myself, nor have I seen this problem in 30 some years of competitive and club riding. That being said, it only takes one accident to end the fun for a long time. Out she goes I guess. I have been switching most of my bikes to Nitto Pearls and the Casati still has the xa while I gather parts. I already have a panto'd 3T Casati stem for the rebuild courtesy of Voodoochile's tip on RBR.
