The Neos rear derailleur is an extremely compact derailleur with
very minimal reach. The ground clearance is much larger than in a
conventional circuit. This significantly reduces the risk of damage!
It was specially developed for small wheels.
This is an inverse rear derailleur - when pulling on the shift cable,
the chain is moved to the smaller sprocket, unlike the normal rear
derailleur. This makes it easier for your child to shift into the easier
gears on hills, while jumping the chain on the larger sprockets is
supported by the spring mechanism of the derailleur!

arshift should be just under the largest pinion. You can precisely
adjust this position with the „low setting screw“ (for the low gear
ratio) (by turning counterclockwise, the cage moves inwards to
-
wards the wheel, turning it clockwise to the outside). This setting
prevents the chain from jumping over the 1st pinion towards the
spoke guard.
3. If the chain produces a rattling noise on the pinions, adjust the
chain with the shift cable adjustment screw. Turning to the right
causes the shift cable to be moved to the left, turning left to shift it
to the right.
An optimal setting is achieved when the adjusting screw is tighte

ned while the crankset is turned and the chain runs over the se

cond largest pinion (2nd gear) until a rasping noise occurs. Then
loosen the adjusting screw again by 360 °. Now the chain should
run clean.
Adjustment of the rear derailleur
The rear derailleur can be adjusted via the adjusting screws and
the shift cable adjusting screw:
1. Turn the shift handle to the 7th gear while turning the crank.
With the „high adjustment screw“ (for the high gear ratio), set the
travel limit so that the upper guide pulley of the gear box is just
below the smallest sprocket when you look at the sprocket from
behind (by turning it counterclockwise) outside, by turning clockwi
-
se inward towards the wheel)! This setting prevents the chain from
jumping over the 7th pinion.
