Hi, my pinch bolt (soft as cheese!) was rounded off, dutifully I drilled it out and managed to remove the crank (part fc-m760) but destroyed it in the process, woops, I found replacement (hope its the right one)
replacement crank arm

but does anyone know when i can get some good quality pinch bolts ? or anyone use some good replacements ?

many thanks

The Shimano ones are perfectly fine. If you managed to round them then you either did them up far too tight or used a really crap allen key.
