It also features a lightweight, newly designed 6000-series alloy frame with a molded footrest platformas well as an all new one-piece bar/stem combination, further simplifying the assembly process. What traits does it share with its predecessor? How about the scuff-resistant tubeless tires, adjustable bar height, fully sealed hubs, high-impact mag wheels, and of course, our industry-leading limited lifetime warranty.
