Firefly Stealth UltraCommuter:: Titanium :: Bertone Edition - Amazing Di2 Integration

For the front end we went a little nuts: we made a titanium bar/stem combo.

We integrated the front and rear shifting into the bars via a couple of brass buttons and a complicated, yet sleek, internal mechanism that Jamie machined and assembled.

The action of the buttons are flawless. Precise shifting with a stealthy minimal look and engaging feel.
