Can anyone help me identify what on earth kind of chainset bolts
my girlfriend has on her Cannondale, please? I sheared one without trying too hard - they are alloy with 5mm hex on both sides - I threadlocked them then had to separate them again- hence the shearing!
If not, I have what appears to be one of those bolts in my spares box. 5mm allen key on one side, 6mm on the other. Goes in a 10mm hole and closes to a little over 7mm. It is silver though.
