    Sin BB Specs

    Hey Gang, my friend just gave me an old mountain cycle sin frame which i'm stoked on but i'm curious what size bottom bracket i need. i'm thinking it's a 68 shell, but not sure what length spindle. Does anyone know the actual specs?

    Should be a 73mm shell but just measure to double check. I'm not aware of any of the MC's using a 68mm shell.

    Spindle length I tend to use 113mm with a triple ring but this could be different if you are using a chain device.
