Hello. I currently use a Kryptonite Fahgettaboudit Mini to lock my bike. The way I transport this lock is that I just lock it on the top tube on my bike. However, which I'm riding it has a tendency of shifting forward and every time I ride over a bumpy surface, it keeps clanking on my top tube. Any suggestions on a good way to transport my U-lock? Any recommended u-lock brackets? Thanks!
