Greetings,
Does anybody here know which Allen key size is required to undo the BBR CNC sprocket adapter's bolts?
I'm referring to the 3 bolts which holds the sprocket itself; as I'm moving from a chain drive to a belt drive, I've been trying to undo them, but a classic M5 Allen key will just spin inside the bolt, unless an M5.5 key is required, which I don't have, I suspect which the bolts may require a SAE Allen tool.
Should you know, could you also gently tell me if the bolts' threads are either metric, Whitworth, or of any other kind?
I'm planning to swap them, along with every other bolts on the bike, with Security Torx bolts, for extra safety against theft.
