Got the new bike this past weekend and used it for the commute this morning. My lights have not yet come in for it, so I just threw one of my PB Superflashes on the back of the rack trunk for now.
For the ride in I wore a pair of RailRiders Yukon pants, merino wool boxers, a poly golf shirt, thin smartwool socks, my regular work shoes and my sunglasses - no cycling-specific clothing, shoes, gloves, etc.
My commute is 4 miles of rolling terrain. I tried to take it easy and spin up the rollers in a much lower gear than I would on my other bikes, while pretty much coasting down. The Alfine IGH 8 speed has plenty of gear range for the terrain.
The last mile is mostly downhill, which is nice for a cool down. When I got into work, I had worked up a little sweat, but really no more than if I had walked a mile rather than rode 4.
