Just received this info via a Nicolai email blast, no info on their site yet:
After G-Boxx 1 and G-Boxx 2 Karl Nicolai is presenting his next coup de main: The B-Boxx is a shiftable planetary gear that is mounted to a regular ISCG adapter and replaces the front derailleur. The B-Boxx is the first product of a co-operation in engineering between Karl Nicolai's company Universal Transmissions and the innovative German bike brand Bionicon. The B-Boxx target is to establish gearbox technology within the ranges of epic and all-mountain biking.
By a simple push-button the biker can choose between two gears. The slow gear equates a crank turn with a 25 teeth sprocket and the force is transmitted directly. The faster gear multiplies each crank turn with a factor of 1,65 what equates a 41 teeth sprocket. During the development some ext ra attention was put on the aspect of shifting under full lo! ad. Like the G-Boxx 2 the B-Boxx is fitted with a patend magnetic activated free-wheel cogging, to make the shifting process smooth.
The B-Boxx will be presented for first time at the Eurobike in September. The rollout is scheduled for 2010.
