Bar Mounts. Re-designed one final time to produce the lightest most resistant to twisting bar mount in Ride Engineering's seven-year history. This one-piece design has removed even more weight than the previous (GEN III) version while further increasing its strength and torsional resistance in the event of a crash. Re-designed to reduce weight again - saves 4 ounces over the original design. Made from aircraft-quality aluminum, precision machined. 3 mm of adjustability front and back. Stainless steel posts resist bending much better than the cheap bolts used by competitors' brands. One-piece upper with 8-pinch bolt design helps keep bars from twisting in a crash.
