The odd cable routing prevented me from using a road fd so I used a barend shifter (friction) for front shifting.
My front der has a low clamp because the seat tube diameter starts expanding in the area where a normal high clamp would fall. If I could have found a road compatible low clamp front der I would have swapped it.
The bar end shifters ended up a better option due to simplicity.
