Interbike 2011 – Calfee’s trick Face plate Light Mount and Custom Di2 Battery With USB
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.
