Hi Tylden,
Hmm, that is a bit of a worry as I thought the problem was with the 22t and thought the 18 might be better. Interesting that you were told it was over torqued as I don't think that was the cause of mine coming apart. It appears to have just un-done the 2 halves.
Did the 18t come apart in two halves or just rip it's insides apart ?
I guess my 22t would have covered a similar distance before failing.
Cheers
