On a more practical note .. I never leave it out of sight anywhere. It's in my garage when not in use and garage is allarmed, has only one point of entry with the up and over Lock and two deadlocks at the sides so feel fairly safe.
Aparently the more discerning theif has found there's good profit on high value bikes using apps like strava to see where you ride from and are even following you home. But, me being a bit lazy, new bike isn't on insurance yet..
