Quite uncommon in Europe, Hive brand is recalling its Revl Carbon calipers. This recall must be taken seriously because it is directly related to the part that clamps the cable. Indeed this part may break in some conditions which could cause serious injuries.
Check the date code of the brakes. The date code is marked on the underside of both carbon arms, and will consist of two numbers and a letter. Brakes with a date code of 41B, 44B, 45B, 53B, 13C and 16C are included.
