Synchron chain
The synchron chain must be re-tensioned with elongation.
Procedure: (The best way is be 2 men or women. One holds the frame and the other adjusts the chain tension)
1. Open the 4 allen screws of the telescopic tube clamp
2. Tightening of the synchron chain: Person A holds the front frame. Person B pulls with his hands at the axle of the
arm cranks until the synchron chain is tightened.
3. Tighten the allen screws of the telescope tube clamp with tightening
torque of 9 Nm
4. Check if the sychron chain does not drag when turning the arm cranks. If the synchron chain drags, than tension
the synchron chain again.
