my ultegra 6750 inner chainring snapped off today whilst cycling which shook me up a littlle bit. i've now taken it to the local bike shop for repair and a new chainring is on it's way. my question is that it's pretty much impossible to find the right chainring bolts and they may have to go on special order. does anyone know where i can get some from as soon as possible with out paying too much for bolts which may cost around 40 quid.
