Never installed blue front and rear cables. These are from the 80’s and have the double crimp barrel. They also have the reduction button end that was designed for bmx. The front cable housing is 24” long and the cable is 5” longer than the cable housing. The rear cable housing is 47”Long and the cable is 5” longer than the cable housing. Color is a match for HARO Masters and Redline RL20 PRo Stylers.
