Shimano has identified a potential safety issue involving BR-C3000-R, BR-C3010-R and the BR-C6000-R rear wheel roller brakes, which were fitted to bicycles sold to consumers after 1 July 2015. Shimano has discovered that some of the affected rear wheel roller brakes can suddenly lose their braking power even when assembled correctly.
To date there have been no reports of incidents. However, as all Shimano products should meet the highest industry standards and in the interest of putting the safety of its consumers first, Shimano voluntarily decided to undertake a recall of the affected roller brakes.
The affected roller brakes are only those with the following production codes: NF, NG, NH, NI, NJ, NK and NL. Roller brakes for front wheels are not affected.
Bicycles purchased before 1 July 2015 are not subject to this recall. Also, affected rear wheel roller brakes that are marked with a white dot (see image) have already been checked and (if necessary) repaired by Shimano and are also not subject to this recall.
Consumers who are in the possession of a bicycle with an affected roller brake should stop using the bicycle immediately and contact their dealer to arrange a free of charge replacement of the brake. Consumers who are not certain whether their bicycle is assembled with an affected rear wheel roller brake, should also stop using their bicycle immediately and go to their dealers to have their brakes checked.
