Something equipped with a Shimano Alfine 8 speed IG hub group, has a disc brake and Front Dyno-hub option.
plus, there is a Brifter made for that hub, though not by Shimano, from these guys :http://www.sussex.com.tw/versa.html
and Jtec makes a Bar-end shifter, to use Drop bars, and the IG hub If that is your wish.
