Its to lock a sub £500 single speed bike which is also insured :)
Fahgettaboudit and Granit 54 were both too heavy for her.
Anyway the use is going to be minimal as we store bikes in the house and she can take her bike in her office.
Decent lock I must say. Seemed like good weight/security balance.
That's another lock I'm considering, although there's a review that says theirs was cropped here:- http://www.evanscycles.com/products/abus/granit-53-d-lock-ec027385#reviews
