Jim installed an Alfine 11 internal gear hub on his green Quickbeam. He had a shop spread the rear triangle to 135mm, and he’s running a thumbshifter on Rivendell Bullmoose bars. He says when (and if) a dropbar shifter for this hub becomes available, he’ll switch to drops.
It looks like he’s using Rivendell’s down tube clamp-on cable stops to run the wiring, and then zip-ties on the chainstay.
Cool setup. One could do something similar with the new SimpleOne without too much trouble.
