12 FUNCTIONS INCLUDING MONTHLY STATISTICS & TWO BIKE OPERATION: BC 12.0 WR displays trip distance, speed, total distance, trip time, clock, total trip time, average speed, average speed comparison, maximum speed, and current temperature. It also provides monthly statistics and can be used on two bikes. The pre-defined tire sizes, ranging from a small child's bike to a 29" bike, make it easy to set the BC 12.0 WR. You can also enter the tire circumference exactly to the millimeter. 

STABLE DATA TRANSFER & MULTI-DAY TOUR TRACKING: The computer's direct cable connection to the transmitter ensures smooth speed measurement and eliminates the need for batteries in wireless transmission. The wired reed sensor with its sleek, slim design is easy to mount on the bike. The BC 12.0 WR measures trip time and distance for even long bike tours. This makes it convenient to read the entire distance of a multi-day biking trips.

LARGE BACKLIT DISPLAY: Slim design and angular shape look good, especially on a sporty bike. The 31 x 41 mm display has room for large numbers that are very easy to read during a ride. Current speed is continuously displayed, and any value can be chosen as the second value. What is especially practical is that the BC 12.0 WR is backlit, so the values can be read easily even when it is dark. Its full text display can be in English, German, French, Italian, Spanish, Dutch, or Polish.

WEATHERPROOF WITH LONG BATTERY LIFE: The BC 12.0 WR is water-resistant and weatherproof, so it can be used at any time. Cyclists do not have to worry about the wired speedometer's battery life, either. The integrated, replaceable button battery (CR 2032) is sufficient to supply the BC 12.0 WR with energy for well over two years. During battery replacement, all total values and settings remain protected. 

EASY OPERATION & VARIABLE MOUNTING OPTIONS: Handlebar bracket can be mounted on the bike with cable ties (included). The bike speedometer can be operated easily and intuitively with its three buttons. The two lower buttons allow convenient toggling among individual functions. The menu button takes the user to the settings and monthly statistics. The BC 12.0 WR can also be used with the SIGMA OVERCLAMP BUTLER or LONG BUTLER handlebar bracket.

Sporty statistician

Whether cyclists are commuting to the office, enjoying a long tour at the weekend, or speeding along on a road bike, the BC 12.0 WR is the ideal companion on all cycling adventures. This SIGMA ORIGINAL likes things sporty and versatile: the BC 12.0 WR provides access to twelve functions, giving cyclists an overview of their performance on two different bikes at all times. The wired bike computer also tracks monthly performance statistics. It is a true SIGMA ORIGINAL with lots of sophisticated functions!

Those travelling outdoors want to know what the weather will be like. The BC 12.0 WR has an integrated thermometer displaying the current temperature. The wired bike computer shows cyclists their personal statistics for the past twelve months. Total distance and trip time can be viewed. This “training diary” allows comparison of monthly activity.

The BC 12.0 WR can easily be mounted on a second bike, whether that bike be a road bike, city bike, or racing bike. After it is set up once, the bike being used can be selected on the bike computer. All that is needed to mount the bike computer on a second bike is a second bracket and transmitter.

The BC 12.0 WR can also be used with the SIGMA OVERCLAMP BUTLER or LONG BUTLER handlebar bracket. The OVERCLAMP BUTLER provides more space and order on the handlebars and a great view of the bike computer. The LONG BUTLER positions the bike computer away from the handlebars and encourages an athletic posture. Both brackets are available separately as accessories and can be mounted on handlebars with diameters of 25.4 and 31.8 mm in a few easy steps. Another security feature is that the bike computer can be fixed to the Butlers with an additional screw to prevent theft.
