I’m a fan of the Nexus 8 and Alfine IGHs. They work well and are relatively inexpensive. One issue is that up until now your choice of shifter was a twist shifter or a trigger shifter. I have both and they work well, but for a drop bar bike a bar end shifter is a much nicer solution.
“Jtek Bar-end Shifter for 8-speed

- Super light weight only 64 grams making it the lightest bar-end shifter on the market!
- 24mm clamp-on design. Easy installation eliminates the need for disassembly to install
- High quality CNC precision machined parts, 100% made in Hugo, MN.

Finally a shifting solution for people who want to use Shimano internal hubs with drop-bar, road bike style handle bars. This shifters is compatible with Shimano 8-speed Alfine & Nexus hubs. It features a clamp-on mounting design which will fit standard diameter 24mm handle bars.”
Cost is $80.00 + shipping. I’ll probably get one of these to try out. It looks like an elegant solution.
