Correct Gear Changing Technique; Internal Gear Change - BH ATOM CROSS PRO Notice

IMPORTANT WARNING
For safety reasons, do not extend the saddle post beyond the
minimum insertion marks.
3.6 Torque limits for nuts and bolts.
The correct spanners should be used in any type of assembly with
the correct torque force. If when you are tightening or undoing
and you notice that the threads are damaged, the corresponding
screws or nuts should be changed. Then, apply the torque limits
corresponding to each size of thread.
Recommended Torque limits
thread sizes (in Nm)
M4x0,7 3 - 4
M5x0,8 6 - 8
M6x1 10 - 14
M8x1,25 25 - 35
M8x1 27 - 38
M10x1,5 49 - 69
M10x1,25 52 - 73
3.7 Correct gear changing technique.
BH bicycles can be equipped with two types of gear change
systems:
- The first is when the chain moves from one gear to another.
- The other, the gear-change system is situated inside the rear hub.
Read the following instructions depending of the type of gear-
change you have:
3.7.1 External changeo
The left-hand gear-change lever controls the front derailleur, and the
right hand gear-change controls the rear gears. Choose the ratios for
greater pedalling comfort and maximum forward propulsion.
You can only change gears when the chain movement is forwards.
Never try to change gears when the chain is not moving or is moving
backwards. Each time you are going to change gear reduce the
force transmitted to the chain, otherwise, the change will be difficult
and the chain and gears will be subject to greater wear. Never
change gear on rough bumpy surfaces.
3.7.2 Internal change
You can change gear when the chain is moving forwards, although
it is also possible to change gear when the chain has stopped or
moving backwards. Each time you change gear reduce the force
transmitted to the chain to facilitate the change. Choose the ratios
for greater pedalling comfort and maximum forward propulsion.
