IMO, the really big advantage of IGH is for a cargo bike. It can be really frustrating to deal with drivers attempting to hook you, crazy pedestrians, and other cyclists if you're regularly hauling 30+ lbs with a derailler drivetrain. It takes space to downshift with a derailler, and quite a lot of the time, I just don't have it. I'm the Person In Charge Of Groceries, for a household of two hungry cyclists. I love my internal gear hub. It is my precious. If I had the option of riding unloaded tho, I'd go singlespeed. They're about the same on maintenance, and it's very flat here.

If you need a 56cm in the Redline 925, they're sold out. It was my partner's first choice of bike since the frame geometry suits him (loooong top tube). His fallback was a Bianchi San Jose. They're very similar bikes, tho the Redline has a few more bits included. The Bianchi is going to be a lot easier to find in person.
