@beecycling @futurebird @MarkHoltom the #ProperLockIt rule of thumb is two locks, different types but both strong (at least one from LFGSS list, if that's still around), each through a wheel, a frame triangle and the parking stand or fixed object. Bolt cutters, bottle jacks and angle grinders are all more common than thieves doing bicycle gymnastics here, but locking only the top tube enables loads of attacks.
