Most of the models that feature the Gates Carbon Drive use either roller or disc brakes. For those who want the no fuss of the belt drive, but don't want or need the weight of those braking systems- take a look at what Civia has to offer. I was researching (read: drooling) my next bike and decided to look at their site (even though there is no dealer in my state ). They have a couple of models that have the belt drive and use canti's.

EDIT: I was mistaken. The Kingfield is the only belt/canti model.
