Breakaway bolts are specially weakened derailleur pivot bolts that are designed to "break away" when a severe impact occurs. Much better to break a small bolt than to strip the threads out of your expensive frame, we think you'll agree! Lightweight too.

Bit More Detail

Thanks for the reply. Digging a bit deeper, there appeared at one time to be two lengths for this part (25mm & 31mm) and some photos show a clip (sort of a wider C-clip) used in the grooves which would act as a retainer.
Hi,

In the entire time we dealt with Middleburn (until they closed down last year) this was the only option that was available so we were never aware there was a smaller length option. Obviously as Middleburn have now closed this is all we're able to offer I'm afraid.

Thanks.
Is This Supposed To Be Used With Spacers?

Hi - I have purchased one of these from you but the free area once attached to the dropout allows the RD to slide left to right - that is, there is more free "bushing" space than the RD mount is in thickness. All I can imagine is a matching spacer is needed to take up the slack? Thanks
Hi,

It will all depend on the derailleur that you are using this with, they were not originally designed to be used with a spacer but if there is still movement with your rear derailleur then a spacer may be required.

Thanks.
