C-Bear Bottom Bracket DUB BB30 R


Precisioned cnc aluminium bottom bracket cup/housing instead of plastic housing.
C-Bear took a very early position not to use plastic cups (back in 2011/12 when most were adding all sorts of plastic accessory parts to force the 2 components – bicycle bottom bracket shell and crank – to fit).
