I received my Kryptonite Evolution 2000 replacement, for which I am very happy.
But I used to use the bracket that mounted it onto the seat tube, a sort of
splined affair that worked quite well.
I saved my bracket, but didn't remove the piece on the U that mated to the bracket.
I am wondering if anyone has discovered a good way to mount the updated orange crossbar Kryptonite locks. Maybe an updated bracket is available, I could see investing in that.
I may just leave this U on the bike rack I use and schlep my cable around,
I did that for about a year.

I think Kryptonite deserves some respect for holding up their end of the deal.

best to all...

PS admittedly there are a lot of Kryptonite threads, but none are active right now except
a very unrelated one in the MTB folder
