Just went to browse the Salsa site for some info and saw a link to a recall for the Cro Moto stems, when I checked it had an update dated May 26th 2010. In doing a search of the forums I only found the recal notice in the Salsa forum from back in '09, since I'd never heard of it and the recent update I though it might be something to post to the General Forum.

The update says ..........................UPDATE 5/26/10 Salsa Cycles has reintroduced CroMoto S.U.L. Stems as of April 26, 2010. These new stems are not affected by the CPSC Recall and can be distinguished from earlier stems by a hash mark on the inside of the stem bar clamp area. The hash mark is on the welded stem clamp, not the removable faceplate. Contact your local bicycle retailer to arrange an inspection if necessary.
