I'm looking for some creative ways to mount or secure a D-lock to pannier rack, without getting in the way of my two Ortlieb Roller bags. I don't wan't to have to put the lock in the bags when moving because 1) they get dirty from chain oil, and 2) they squash or bruise perishables, unless you put them in the bottom of the bag, which is a faff when loading shopping. You can't just load up your bags at the till or market, because the locks are always on the bike outside the shop and therefore last to go in the bag. I'm currently using a Tubus Logo rack, and the top of the rack is free, but struggling to secure my full sized Kyrptonite New York lock with basic bungee cords, It's working free on bumpy roads which is obviously quite dangerous! I have placing the D lock around the frame of the rack, however can't quite get it secure either, even with the bungees. Thoughts?
