While I only awarded the Abus Granit Super Extreme 2500 4 out of 5 stars when I tested five of the best angle grinder-resistant bike locks early this year, it really only fell short in two areas. Let me explain...
The first of which was its performance in the angle grinder test itself. This testing was so close, almost too close to call. None of the locks failed; it was nearly impossible to differentiate them, as the cut depths differed by mere millimetres.
