Crank bolts for Miranda cranks on Reign E+?

[Donamici]

Fitting shorter Miranda cranks to the Reign E+2, does anyone know what crank bolts I need to get? Link?

TIA

I got these ones as the self extracting type were out of stock everywhere. They were cheap and they did the job fine. It looks like that listing has ended but there are plenty of similar ones out there. Any that fit ISIS axles should fit afaik.

First ride since fitting the 155mm cranks. Got a couple of pedal strikes, but generally felt a bit more confident to throw in a pedal stroke or two over chunky terrain.
