Callouts: 166 [?] 98 99 506 [?]

ADVANTAGES

The handiest gear.
Fitting very simple.
It operates even if cable breaks by simply disengaging spring 98.
It allows the use of freewheels with any number of cogs.
It stands up to rough usage and always maintains its performance.
Very fast and silent.
It lasts for a long time owing to its accurate workmanship.

INSTRUCTIONS FOR FITTING

1. Ensure that the gear is fitted in line with chainwheel and that screw 166 is very tight.
2. Be certain that chain is long enough to allow using the largest chainwheelring with the largest freewheel cog.
3. Adjust the two screws 99 so that the chain cannot jump off from outside cogs of the freewheel when changing gear.
4. If the freewheel is too near to the spokes, fit the spacing ring 651.
5. To give more or less tension to the chain, remove spring end to another hole and tighten screw 506.

N.B. When cable breaks, the gear may still be used by disengaging spring 98.
