BC 12.0 WR
One for two bikes
This SIGMA ORIGINAL likes things sporty and varied: The BC 12.0 WR offers you twelve functions that give you an overview of your performance on two different bikes at all times. The wired bike computer also provides monthly performance statistics. It is a true SIGMA ORIGINAL with lots of sophisticated functions!
Versatile thanks to twelve functions
The BC 12.0 WR is the ideal companion for all your cycling adventures. It captures monthly statistics, displays the current temperature, and can be used on two bikes.
An eye on temperature
If you are going somewhere on a bike, you want to know what the weather is like. The BC 12.0 WR has an integrated thermometer, showing you precisely what the temperature currently is.
Stable data transfer
The speedometer’s direct cable connection with the transmitter ensures smooth speed measurement. The BC 12.0 WR needs no battery for a transmitter, and you can use your bike computer for years without changing its battery.
Can be used for two bikes
Which bike do you want to use today? Road bike, city bike, racing bike? If you ride different bikes, you can easily use the BC 12.0 WR 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, which you can find in the SIGMA online shop.
Predefined tyre sizes
Just a few clicks, and you’re ready to go: Thanks to the pre-defined tyre sizes, ranging all the way from a small child’s bike to a 29″ bike, setting the BC 12.0 WR is effortless. You can also enter the tyre circumference exactly to the millimetre.
When the ride is over, the BC 12.0 WR’s usefulness has just started. The wired bike computer displays your personal statistics for the last twelve months, including total distance and ride time. This “workout diary” helps you compare your activities on a monthly basis.
Large backlit display
The BC 12.0 WR’s slim design and angular shape cuts a nice figure, especially on a sporty bike. At 31 x 41 mm, the display is larger than its predecessor. That provides room for large numbers that are very easy to read during a ride. An extremely practical feature is that the smart bike computer is backlit, so you can easily read your values even when it is dark. The BC 12.0 WR displays current speed continuously, and you can select whatever second value you want.
You can set and operate the bike computer intuitively with three buttons. You can use the two lower buttons to conveniently toggle among the individual functions. The menu button takes you right to your settings and monthly statistics. The BC 12.0 WR is multifaceted but still easy to use! Your ORIGINAL is practical: its integrated start/stop function begins measurement as soon as you start your ride and stops when you take a break or finish.
The BC 12.0 WR’s bracket can be quickly mounted on the handlebars or stem with two cable ties. You can attach the speed sensor the same way. The computer receives all the necessary data wiredly. You can remove the bike computer any time and stow it conveniently – and attach it to the bike again just as quickly.
For orderliness and a perfect view:
the over clamp butler
You can also fix your BC 12.0 WR on your bike with the SIGMA Over Clamp Butler, which is available from the online shop as an accessory. It gives you space and order and an ideal view of your device. You can use a screw to secure the BC 12.0 WR against theft. The Butler fits handlebars of 31.8 and 35 mm diameters.
Long Butler for an athletic posture
The Long Butler creates more space from the handlebars and promotes an athletic posture. The bracket can be mounted on handlebars with diameters of 25.4 and 31.8 mm in a few easy steps. You can use a screw to secure the bike computer against theft. The Long Butler is available as an accessory in the online shop.
Saves your multi-day tour
The BC 12.0 WR measures exactly how long you have been on the bike during your tour and how far you have ridden. You can conveniently measure ride time and distance for a multi-day cycling excursion.
Bicycle inspection reminder function
A bicycle needs regular maintenance, because it reveals defects in the brakes, chain and tyres. Thanks to the service interval, the BC 12.0 WR reminds you to have your bike inspected after 750 kilometres. The service interval is therefore a helpful feature for your safety and appears for a total of five times after switching on the device.
Reliable and thrifty
A button battery (CR 2450) supplies your BC 12.0 WR on all your tours for more than two years without being charged. During battery replacement, an integrated chip stores all the values and settings.
Water-resistant and weatherproof
The wired BC 12.0 WR is water-resistant, so it can be used on your biking adventure regardless of the weather.
The wired BC 12.0 WR is quite the linguist. Its full text display can be in English, German, French, Italian, Spanish, Dutch, or Polish – seven languages in all.
