I just read a thread on C & V earlier today about brake calipers for a Trek ???? Someone showed a closeup of the calipers where you attatch them differently. Maybe these require those types of calipers. I'll see if I can find the post.

Oh never mind. My mistake.


Update: so if you look on Kool Stop page right next to those finned pads are replacement pads. That page says they're replacement pads "for the popular Magura HS33 and HS11 brake systems:

So they must fit those types of brake systems. I looked them up and they look pretty different from what would be on a C & V bike.
