I have an XT Di2 groupset I'd like to mount on my old 26" Pivot Firebird, with the front derailleur.

The Firebird has no bottle mounts and I'm running a RS Totem coil fork with a straight 1.5" steerer, so no easy way to mount the internal battery. I want to mount a battery externally.

Any ideas for the best way to do this and the most appropriate battery?

I ended up going with the Shimano SM-BTC1 battery mount. I used velcro straps to hold it on and it seemed to work well.

The issue I had was the front derailleur hitting the frame. So I put all the Di2 ontp my Evil Sovereign, with bottle mounts. Works well there too.
