MAGNUM Brake Line - Upper - 7/16" - 21" 37921

Stock brake lines expand under pressure, compromising stopping power and feel when you need it most. The MAGNUM Upper Brake Line eliminates that mushy response with PTFE inner tubing and aramid reinforcement, delivering the firm, consistent braking performance that serious riders demand. Built with all-brazed manifold construction and AN-3 connections, this line installs cleanly without leaks or alignment headaches.
