Beyond having some very nice stuff from eecycle works mounted up in their booth, the guys at Calfee were also sporting some trick stuff of their own. First up, I spotted a very odd looking stem faceplate and asked what was going on there. I was told it is an early prototype that is a socket to hold an LED light. The stem faceplate is somewhat universal-ish from what I am told, so with any luck it will fit a variety of stems. However, if you are paying Calfee for a full custom bike, I have a feeling one might spring for a custom bar-stem setup with fully integrated wiring. The light should have around 200 lumens output. Look for more details plus a finished product at NAHBS in March.
Head on over to the other side for more images and details.
The power for the light will come from a battery mounted in the steerer tube, and the port to charge the battery will be in the top cap. That same power source can also power a Di2 set up, and has a USB dongle for charging up your gadgets should it be needed.
The screw on cap should help keep the elements from damaging the USB port.
