Not that I want to steal sales from CRC but isn't that just a bent spoke, made one in the workshop by wrapping a spoke once round a marker pen and hey presto a tool that lasts years and years!
Worst part, any cable hanger (ie chill pill, Ringle 'peace off' etc) that used stupid size keys to tighten. Put any force on them and the bolt or the key rounds off a treat never to be moved again.
