This bike computer likes things sporty and varied: The BC 12.0 offers you twelve functions that give you an overview of your performance on two different bikes at all times. The speedometer also provides monthly performance statistics. It is a true SIGMA ORIGINAL with lots of sophisticated functions!

If you ride different bikes, you can easily use the BC 12.0 WL on your second bike, too. After setting it up once, you can select the bike you are currently using on your bike computer. For mounting on a second bike, you will need an additional bracket.

In the wireless (WL) version, the digitally coded STS radio protocol moves your data from the speed transmitter to your bike computer. This protects data perfectly while it is being transmitted to the BC 12.0 WL and eliminates external interference.
