grooves 6 a f as shown in fig4 and 7 the additional structure may take the form of spacers 8 a 8 b 8 c attached between the stationary supports 5 a 5 b the spacers 8 a 8 b 8 c add rigidity between the stationary supports 5 a 5 b and in one embodiment are located near the outer circumference of the stationary supports 5 a 5 b in one embodiment the stationary supports 5 a 5 b are connected to the spacers 8 a 8 b 8 c by bolts or other fastener devices 45 a f inserted through holes 46 a f in the stationary supports 5 a 5 b referring back to fig1 and 3 the stationary support 5 a is fixedly attached to a stationary support sleeve 42 which coaxially encloses the hollow shaft 10 and extends through the wall of the hub shell 40 the end of the stationary support sleeve 42 that extends through the hub shell 40 attaches to the frame support and preferentially has a non cylindrical shape to enhance subsequent attachment of a torque lever 43 as shown more clearly in fig7 the torque lever 43 is placed over the non cylindrical shaped end of the stationary support sleeve 42 and is held in place by a torque nut 44 the torque lever 43 at its other end is rigidly attached to a strong non moving part such as a frame not shown a stationary support bearing 48 supports the hub shell 40 and permits the hub shell 40 to rotate relative to the stationary support sleeve 42 referring back to fig1 and 2 shifting is manually activated by.
