There are different versions of the Ampero 4850.
This version, LH/SP (NKR) I have now established is only suitable for bike frames built with the appropriate fitting for these types of lock - which you attach with supplied bolts and mounting plate.
The CL version is appropriate for aftermarket fitting, and comes with specific bands to attach the lock to the seat stays of your bike. (However even the CL version may be unsuitable for some bikes with the rear derailleur cable routed down the seat stays).
