I'm into my second season on the '11 Acme. I'm riding 11 miles round trip over hilly and wet Seattle. I had some initial problems with the Alfine 11, but Aaron Goss, the IGH Wizard sorted them out. Since then, it's been maintenance free and a total delight.
I also like the hydraulic disk brakes. They are very sensitive and easy to keep set up.
The only thing I notice is that I never use the top gears, but would love one more lower.
My wife is a bike snob. She loves her carbon road bike, but loves the smooth feel of this bike for riding around town. I'm tempted to order her the Ajax - the 8 speed little brother to the Acme.
