My GT ZASKAR - Rebuild - Avid Single Digit 7 Brake System. I was originally looking at NOS/vintage Shimano XT rim brakes, but I read great reviews that these were actually better brakes than the Shimano of the era. so I found sets for both ends. They were right. For rim brakes of that era, I was impressed with their feel and actual stopping power. The NOS - ROCK SHOX Judy SL, was a great addition to this build. I would actually say that it was a bit "ahead of its time", as it actually works on legit, modern Single-track trails.
