Type b
This sporcket have hub on both sides which provides more stability and support to the sprockets
Type c
Sporoekts have a split design
Type d
Keyless adapter hubs advantages
High durability against reversing or shock loads
Accurate and secure axial positioning
. No key to fit
. The capability of handing high tourque without long keys
