I have laced 100mm hoops to a trike hub, two sets. I would suggest that you measure everything you intend to use to get an idea of clearance first. The really weird thing in this application is the angle of the spokes on the finished wheel. Almost any other wheel build will result in spokes that angle outward from the rim to the hub. Not so on this applicaton, you end up with an almost straight line! I found out that i had to do my radial adjustment (outside diameter) first, then my lateral (side to side) for the tension/true to be succesful. If you end up having small clearance issues, than a dish can be done to correct it. As far as brakes, you probably already have a braking system in place that is functional, why change it up? There is also the possibility of having a braking system on the front wheel alone as well. :wink:
