Shimano recalls alloy pro vibe stem models

Shimano Europe (owner of the Pro brand) has issued a recall for certain batches of its Pro Vibe alloy stems. 

Shimano has issued a stop-riding and recall notice on all alloy Pro Vibe stems that have been sold since May 2020. After discovering certain batches can develop cracks in particular conditions. The stem models affected by the recall can be identified by the silver ‘V’ branding on the faceplate and the forward-facing mounting bolts. Carbon stems are not affected.
