Good quality. Quick and easy measurements
The test fit card is a convenient method of measuring cage bearing sizes.
Don't even know where to begin. The upgraded skiff bearings I swapped for the stock bearings are godlike. Old bearings had 8 steel balls and was stamped, the skiff bearings I received were 12 ceramic balls completely caged, not stamped. Glide as smooth as.... uhhhh.... something really smooth. The cheat sheet is awesome, too! A lot more helpful than I realized it would be when I ordered it. Can't always trust other people's calculations, good to be able to do it yourself. Thanks, Mr. Skiff!

Perfect example of being efficient. Just as you’d test nuts and bolts, this helps ,ale sure these little parts end up in the right place! Nothing more frustrating than to finish assembly only to realize you have the wrong bearing installed. Plus it’s from Skiff, so you know it works right. It’s what they use.
