Fitting SRAM chain catcher to my daughters new frame. The length of bolt supplied with chain catcher is same as existing bolt, hence too short to fit front mech with extra width of catcher!! SRAM force mech to braze on hanger for this application.

Simply I need longer bolt and need to determine correct bolt type which seems impossible from net. Its currently 4.7mm diameter and 22mm long, i need an extra 7mm length so 30mm. What is thread size eg m5? Any one know sizes?

And why can't they simply supply a longer bolt with catcher.....

I expect it's an M5.
