Kool Stop Eagle 2 Smooth Stud for Cantilever Brakes Salmon
This is the classic choice where it fits. The Eagle 2 will fit most rear brakes, but due to the long rear section, there may be clearance problems in some front brakes. If your rim/forkblade clearance is tight, you should choose one of the thinline models, or the Continental.
the Eagle 2 has all of the special Kool Stop features described above.
