Empella, Spooky and some of the TRP knockoffs,'eurocross' ,
that are formed somewhat like old Mafacs,
out of 2 pieces of aluminum joined by the bushing and the pad holder , have been modified
to put a barrel adjuster under the head of the transverse cable, because they can.
Oh. and Kool stop makes some brake shoes that come apart
Shoe comes off the post, without changing the adjustment.
