This castle has been living for about 5 years in the Mediterranean; o) Salzburg, will run daily in summer and winter and always with attitude.
No matter what the weather, whether or not sub-zero temperatures; o) it works fine - but have to admit 1x year comes in a bissl WD 40, as with any lock.
Holder: Who is dissatisfied with this mount, to the competition (eg: Kryptonite) on market times View - perfect for me, rattles nothing, cleaned up.
Plastic screws: Yes, mine are also partly filmed, because I did not pay enough, but I prefer I turn from the Phillips, as I turn an iron bolt and threaded through the bracket in the bucket.
To replace the bracket to another bike I can only say that it will work if the seat tube diameter are similar.
