How wide is the Classic when it has a regular C bearing in it? Also, how wide is its gap with a regular bearing put in?
I’m going to go out on a limb and say that most any YYJ with a regular bearing in it is the same gap size.
Hitman X: Gap Width: 4.68 mm / .18 inches
DM II: Gap Width (mm/in) : Narrow Bearing: 3.00 mm / .12 "Speed Bearing: 4.95 mm / .19 "
YYJ Classic: Gap Width(Small Bearing): 3.1 mm
So .19 in. or 4.7-5.0 mm for the classic. You will see a big difference w/the speed bearing.
