    Coaster brake of Nexus 7 parts

    Hi,
    I broke my breaking "shoes" of the internal gearing system (Shimano Nexus 7). This is the broken part




    The guy at a generic sport shop told me to replace the wheel... Is there a more reasonable solution. Does shimano sell those parts?

    Best regards,

    Most Shimano stuff don't have replaceable parts or for that matter can not be service . The best you can do is find another junk hub like your and use parts from it . Or replace the wheel or hub .

    Since they list parts, they should be available.....

    IMO, it's never necessary to replace an entire wheel when only the hub has failed, although one might want to for other reasons.

    i would first contact, by phone is best, shimano and ask if the shoes are available for a nexus 7 hub and go from there. the alternative, asking someone at an LBS for that type of information, has often been less than satisfactory. best to try to contact someone on the phone or a "chat" line.

    BTW, i'm impressed anyone has put enough miles on a nexus 7 hub to really wear out the shoes. congratulations! i have to say that i would be wondering about how the shell is holding up...

    As Huey said, talk to Shimano. Since you've got a part number, you'll be able to find out if it's available. If Shimano isn't helpful, talk to Aaron's in Seattle:

    Thank you. Fortunately the shell is in pretty good shape.

    I will contact Shimano and I will let you know.

    I think in the worst case I will have a less efficient break (I have an independent one on my front wheel) in the back. Since I removed the floating broken part, it is better.

    pretty much any bike shop can order from shimano direct. shimano in the bike world does not deal directly with customers

    If the parts aren't available or are prohibitively expensive, could you fit a caliper brake to the rear of the frame and add a brake lever for it to your handlebars?
