Features: By raising the original diameter tubular handlebar, it provides a more upright and comfortable riding position. It enables cyclists to have a more comfortable riding posture and effectively reduces fatigue during long-distance riding. Made of high-strength aluminum alloy, CNC machined with high quality and anodized surface. Handlebar risers also reduce fatigue when riding while standing, which is especially beneficial for taller riders. The overall result is a significant increase in endurance and focus. Long stretches on the highway are less nerve-wracking, and even fast, difficult off-road sections are easier to handle. It's easy to get used to it in minutes. No long cables or brake cables are required to fit the original handlebars.
