The Chrono Rotary Forged® Wheel /RF™ Wheel is manufactured using a highly advanced production technique called Rotary Forging® /RF™. The rim of the wheels is forged at high pressure while the wheel is spun at high speed. This alters the molecular structure and enhances the strength of the alloy. The benefit is a much lighter weight than a regular cast wheel. Most importantly, the weight saving is in the outer rim of the wheel which dramatically reduces rotational mass and enhances vehicle performance. The Chrono is a sports wheel infused with TSW’s Rotary Forging Technology. It’s sporty split 5 spoke design incorporates an ideal depth to height ratio balancing good looks with rotary bending fatigue. It also features an undercut lip to shave extra weight to achieve ultimate performance.
