DIA TEC HAD TO MAKE SOMETHING TO COMPETE WITH THE 990 SO HERE IT IS. IT DOES HAVE ONE BETTER POINT OVER A 990 ALSO. FOR THOSE RUNNING A SMALLER SPROCKET (25TOOTH OR 28TOOTH) IN THE FRONT THIS BRAKE IS LOW ENOUGH TO STAY OUT OF THE WAY OF YOUR CHAIN ON MOST CURRENT FRAMES. COMES WITH THE STUFF TO MAKE IT WORK ON THE FRONT OR THE REAR. SOME PEOPLE ARE ALWAYS THINKING!! PRICE IS FOR ONE BRAKE.
