SIGMA BC1106 DTS Wireless Bicycle Speedometer
The BC 1106 with its diversity of functions is the right choice for the athletically ambitious biker. The integrated storage chip prevents loss of pre-settings and total values during power losses or even battery changes, with low power scenarios announced in due time by the low battery indicator. Two wheel size settings are possible, which can be recognized automatically with an optional Bike 2 Sensor, allowing riders to use their BC 1106 interchangeably between any combination of two bicycles.

Digital Transmission System (DTS) Explained
With 2-channel radio transmission (km/h and pedal frequency) and 100% digital encoding without data loss, the DTS system guarantees 100% data security of current speed and pedal frequency values during wireless reception. It does this by calculating all relevant data, encoding it and transmitting it in data packets to the integrated receiver in the bike computer. Disturbances such as power lines or mobile phones are no longer a problem as transmission is carried out over the so-called low frequency. A double security system also ensures that only the data packets from your own transmitter are evaluated by the receiver. This means that group rides are no problem.
A further security measure is redundant data transmission so that no data can be lost. The size and quality of the receiver has also been optimized by a specially developed SIGMA chip (ASIC) and integrated into the bike computer which also saves on battery life.

User Ratings and Reviews
5 Stars Great Computer
Easy set up and directions and great functionality. No problems what-so-ever picking up the wireless signal.
2 Stars Not very good, Blackburn is better
This one actually made me truly appreciate my Blackburn Delphi 4.0, even for all its own issues, it was so much better than this one. This one takes forever to sync after going to sleep and sometimes never does, almost always have to hit a button to wake it up. I’ve tried adjusting the sensor distance and gap, that’s not the issue. What is really awful is the accuracy and slow pace of updates. This reads ONLY IN .5 MPH INCREMENTS! That means accuracy is +/- .5 mph or AS MUCH AS A FULL 1 MPH! Furthermore, updates seem to be infrequent, as is obvious when braking. I’ll be at a dead stop for 3-4 seconds before it reads 0 mph. If you are a cyclist who seriously uses a cyclometer for feedback, this one is useless. There is no good way to tell if the gear change or extra effort you just put in are getting you any acceleration… things that are almost intuitive with the Blackburn, which reads to .1 mph and seems to update real-time. Oh, and those godawful rubber bands for mounting… Sure they are easy… until you screw up and one goes flying never to be seen again… And when you are done, the head unit swivels around the handlebars requiring adjustment constantly. This is really only a good cyclometer for casual users and kids. I would never recommend it to anyone who has a serious need for real-time and accurate performance feedback. I will be buying a Blackburn Delphi again soon. Even if it dies again after a year (note, a year for me is 8000-10000 miles, so expect yours to last longer), it’s a better deal because it does the job I need. This one is just a waste of handlebar space.
2 Stars Not weatherproof
At the begining this product was working perfectly, to my surprise because this computures usually give you a hard time. This was until I went to to a trial with losts of water and lots of rain, and some water must have gotten into the trasnmiter, because it wont work anymore. The display turns on fine, but wont receive any signal. I believe, these wireless computers are not worth it, for this reason. It worked fine about 3 or 4 times. Lost my money.
