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 brakes have been fitted to new bicycles sold by many different bicycle brands.
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.
