Overall Rating: ★★½☆☆

The BC 1106 with its diversity of functions is (not really) the right choice for the athletically ambitious cyclist. While the idea of going wireless is a great concept, the computer requires 3 batteries. One each for the transmitter, receiver and computer. At any time these batteries will die causing the rider to have to investigate which is the culprit. There is a button on each of the components which can be pressed to indicate if the battery is good or bad (a green light will indicate a good battery). As well, the transmitter does not have a wire attaching it to the bike or computer so should the rubber band fail, the transmitter could be lost. Finally, through vigorous testing in race and training environments, the signal from transmitter to receiver can be easily corrupted, either by water or misplacement of the transmitter, etc. We feel that a better computer can be had in the “wired” version of this computer, Sigma 1606L.
Some good feature of this computer however, are the integrated storage chip which prevents loss of pre-settings and total values during power losses or 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.
