Thanks for the input guys. I'm looking forward to getting this bike trail worthy. I wasn't a bmx-er. Although I had a bunch of friends who were when I was a child living in California in the 80's. I have no experience with U-brakes. Cantilevers and V - brakes have always been my go-to. I got my first mountain bike in 1997 so that is the era that I'm most familiar with.
