A few manufacturers do an 8mm chord option, instead of the more normal 7mm or 7.4mm chord. Obviously 6mm "comp" chord will be useless!
I would recommend at least 7.4mm, and if its overhead, the 8mm option would be the preference.
Read the fine print on the packaging.
Some manufacturers sell Chord, so if it has an allen key screw, you can actually replace the chord, and keep using the Ankle Strap and Rail Saver.
If it is Aussie Made with the "rivet" (non allen key) option, try sending it back to the manufacturer for a replacement chord.
The 3 R's, Reduce, Reuse, Recycle !!
Three it's a magic number
Yes it is, it's a magic number
Because two times three is six
And three times six is eighteen
And the eighteenth letter in the alphabet is R
We've got three R's we're going to talk about today
We've got to learn to
Reduce, Reuse, Recycle
