Hey guys, I've been mulling over getting a top box on the back of my bike for a few months now. I need a place to put my excess gear into when I change to go running. The bike gets left in an open car park for a couple of hours whilst I'm trail running. I haven't found one box that really convinces me (price and looks), and I'm now leaning towards a pack. Possible a small Kreiga or Wolfman. The thing is, how do I lock it down onto the bike so that it can't be easily opened or removed? Sure, if someone is really determined to have a go at it they will cut it loose or at worst cut the pack open. But realistically I don't think that is likely to happen in the place where I will be leaving the bike unattended. Are there any straps available that can be locked down, or straps made from material that can't be cut so easily? I'm guessing the packs themselves can be sealed by padlocking through the zippers or closing mechanisms. Any ideas gratefully received!
