It's nice to have a wider range of Settings.
I had been using NCY's Pulley face for about 20,000 km, but the face surface was starting to wear off, so I looked for a new face and bought this one.
NCY has been used up to now.
14 degrees 90g Flat where the boss hits
The new KOSO is
13.8 degrees, 114g, Type with a dent where the boss hits.
The angle of the Face surface is not stated in the product description, and after inquiring with KN Planning, we were told that it is 13.8 degrees.
I didn't have room for a Bose Washer at NCY.
KOSO can add as much as 0.5mm without difficulty, so the range of setting is wider.
