It would seem that the latest version of the stop can go one wider. So if you are a bit stuck and the normal 10mm rope is a bit muddy or frayed and expands you have somewhere to go.  .. I'll get my coat...

Nice to see that they have used stainless steel bobbins

Hi, The original Stop did 11mm but was very slow on it! I understand that the bobbins aren't replaceable though.
