Cool. That means a Masi, lets say $750, Alfine rear wheel, lets say $300, and the Alfine brifter, lets say (big guess here, ? $150 ??? I really have no idea) and you have $1200 invested in a IGH bike with a Single Speed wheel ready to drop in, and some labor to do to swap out all the parts and stuff. Personally, I would pay more for the Dynamic bike if I liked it and save myself the work.

My other idea was to use the bull-horn handlebars, put the brake levers underneath near the end, and bar end shifter for the Alfine. Then I could brake and shift from one hand position. I saw a single speed at Navy Pier a few weeks ago riggled like this ( minus the alfine and bar end shifters, obviously) and I liked what I saw. I want a look at the Dynamic before I go that route, and I need to put my Giant Seek1 with the Alfine IGH through some road trials when it warms up to decide if I like the Alfine enough to build a bike around it. Currently the Seek1 with Alfine is set up for winter with studded tires, and that is no way to properly evaluate a bike for summer road use.
