Over the years, aluminum frames have earned a reputation as being overly stiff and providing poor ride quality compared to their carbon brethren. The engineers at Trek have made it their mission to challenge this assumption, using methods that allow the material to retain its best characteristics—its lightness and strength—while simultaneously improving ride quality. Many cyclists enjoy the responsiveness that comes with stiffer aluminum frames. Unfortunately, what starts out as a snappy, fun ride can quickly become uncomfortable and fatiguing on long or rough outings, making aluminum a poor choice for endurance and adventure-minded riders. Alpha Aluminum was developed to build more compliant frames that retain the acceleration and affordability that have always made aluminum popular. By taking a comprehensive approach to frame design and construction, Trek is able to fine-tune frames to be stiff where necessary and compliant where possible. The result is a more enjoyable ride that expands the opportunities for you to comfortably enjoy your aluminum frame. With Alpha Aluminum you won’t have to think twice about hitting the gravel or signing up for a multiple-day tour. More than ever, an aluminum bike is the only bike you’ll need for recreation, touring, training, and competition.
