Yes, please! Found on Black Cat Bones’ blog, this little project looks sick. We’ve contacted them for more info but just couldn’t wait to post this.

UPDATE: Just talked to Gerard Piedra, one of the owners of BCB. Here’s what he had to say:

“This was an exercise for us. We wanted to explore the Shimano Di2 system, but the original thesis goes way deeper. This is just the tip of the iceberg. We have developed a complete electronic mountain bike system, including the shifters and derailleurs.

“We are now working on producing more prototypes. Black Cat Bone is a small company. All of us work in other things to fund what we’re doing, and the situation right now is we are trying to find a partner to help get the machines necessary to make more prototypes.”

While we’re waiting on this to become real, check out their single legged carbon fiber fork, used on the Crumpton 29er prototype in Fair Wheel Bikes’ Interbike booth.


  1. The world (of cycling) has gone mad with electric shifting and disk brakes on road bikes. I’m curious to see what comes out in the wash…

  2. Brilliant, one of those, “why the hell didn’t I think of that,’ moments. What’s really cool is the idea of being able to mod the shifter and get rid of the muliple indexing. One shift in either direction changes gears.. Time to go experiment 🙂

  3. BlackCat Bone has got to be one of my favorite companies in cycling. Always coming up with cool new ideas (and actually making them work!).

What do you think?
