The Kryptonite Evolution Mini is what I use on my Trek XO-1 cyclocross bike. It's kinda like you're 7.2 given the wider wheel clearance. This means if the pole you lock to is a standard meter size then you won't be able to lock your back wheel. But then again, this just motivates you to do the right thing and bring a secondary cable lock. The Evolution is a great lock. It's thicker and even a little heavier than my standard Kryptonite lock.
