Bicycle electronic system
A bicycle electronic system including: a manual command management unit, having a casing configured for being fixed at a handgrip of a bicycle handlebar, that includes at least one first manually actuatable switch and a first processor; a derailleur management unit comprising a second processor; and, a first direct communication channel that connects the first processor and the second processor. In response to the manual actuation of the at least one first switch, the first processor emits a derailleur command signal addressed to the derailleur management unit, and the second processor receives the derailleur command signal from the first processor through the first direct communication channel.
1. A bicycle electronic system comprising:
a manual command management unit having a casing configured for being fixed at a handgrip of a bicycle handlebar, comprising at least one first manually actuatable switch and a first processor,
a derailleur management unit comprising a second processor,
wherein the system comprises a first direct communication channel that connects the first processor and the second processor,
wherein the first processor, in response to the manual actuation of the at least one first switch, emits a derailleur command signal addressed to the derailleur management unit, and
the second processor receives the derailleur command signal from the first processor through the first direct communication channel.
2. Bicycle electronic system according to claim 1 , further comprising a second manual command management unit having a casing configured for being fixed at a second handgrip of the bicycle handlebar, comprising at least one second manually actuatable switch and a third processor.

4. Bicycle electronic system according to claim 3 , further comprising a second direct communication channel between the third processor and the fourth processor, and the third processor, in response to the manual actuation of the at least one second switch, emits a derailleur command signal addressed to the second derailleur management unit, and the fourth processor receives the derailleur command signal from the third processor through the second direct communication channel.
5. Bicycle electronic system according to claim 4 , further comprising a third direct communication channel between the first processor and the fourth processor, and the first processor, in response to the manual actuation of the at least one first switch, emits a derailleur command signal addressed to the second derailleur management unit, and the fourth processor receives the derailleur command signal from the first processor through the third direct communication channel.
6. Bicycle electronic system according to claim 5 , further comprising a fourth direct communication channel between the third processor and the second processor, and the third processor, in response to the manual actuation of the at least one second switch, emits a derailleur command signal addressed to the derailleur management unit, and the second processor receives the derailleur command signal from the third processor through the fourth direct communication channel.
7. Bicycle electronic system according to claim 6 , wherein at least one of the direct communication channels is a wireless communication channel.
8. Bicycle electronic system according to claim 6 , wherein at least one of the direct communication channels is a cabled communication channel.
