Hydraulic Road Disc Brakes: Shifting Update!

Following up on my post on Di2 shifting options and the Fair Wheel Bikes Di2 hack, I’ve looked a bit longer at the Calfee Design Di2 battery modifications displayed on a titanium frame from Vuelo Velo. Looks like Calfee has actually been doing this for a few months now and can also retrofit other carbon frames for the internal Di2 option. Here is the core of their kit:

Also turns out that my old buddy Mike is now working on promotional type stuff for Calfee…and his brother and other buddy, Ian, owns a shop in Waco, Texas that is taking delivery of some really nice Calfee rigs. Ian’s own personal bike is simply incredible – not to mention WHITE! – and employs the internal Di2 setup. Apparently Ian will also be on Calfee’s new “Adventure” frame for gravel road riding as well. Take the following as a teaser; he’s got gobs more photos on his shop’s site…but that white Specialized crank setup (on a PressFit 30 bottom bracket, I would assume) definitely warrants a picture here on BB:
