Erling,

I use the very same model of Abus lock and like it a lot. Where do you keep it while riding? I used to affix it to a rare rack, now that I use a different style rack, I keep my lock wound in a backpack. The lock is pretty heavy though.

I also noticed it is getting tough to wind/unwind the cable when the temperatures drop well below freezing...

Thanks.
